Natural Family Planning: The Importance of the Mother to the Baby


One of the benefits of God’s plan for spacing babies with the right kind of breastfeeding is that the breastfeeding relationship keeps the mother with her baby.  I’d like to share some thoughts on this from Saint John Paul II.

On Human Work: 1981
“To take up paid work outside the home is wrong from the point of view of the good of society and of the family when it contradicts or hinders these primary goals of the mission of a mother.”
“Mothers have an irreplaceable role.”

Address to “Women, Wives, and Mothers,” Familia et Vita, January 1995.
“Women can never be replaced in begetting and rearing children…  Women as mothers have an irreplaceable role.”
“The children also have a right to the care and concern of those who have begotten them, their mothers in particular.”

The Gospel of Life: 1995
Sincere gift of self by the mother: “daily heroism”  “brave mothers”  “heroic mothers” (86)
Baby: “Every human being” is “an icon of Jesus Christ.” (84)
“The family is the sanctuary of life.” (6, 11, 59, 88, 91, 92, 94)

May 12, 1995 address to scientists at Vatican breastfeeding conference.
“No one can substitute for the mother in this natural activity.”
“This natural activity benefits the child and helps to create the closeness and maternal bonding so necessary for healthy child development….So vital is this interaction between mother and child that my predecessor Pope Pius XII urged Catholic mothers, if at all possible, to nourish their children themselves (Oct. 26, 1941).”

Sheila:  God’s plan for spacing babies has many benefits.  Not only the spacing but also health and emotional benefits for both mother and child. 

Let’s pray that our government and our Church with the Pope, cardinals, bishops, priests, and teachers will promote ecological breastfeeding because of these many benefits.

Natural Family Planning and Unchaste Behavior

Chapter 1 of our NFP manual, Natural Family Planning: The Complete Approach, is a New Evangelization effort.  Section 6 of that chapter is titled, “The Bible and Church teaching on contraception.”  There we present biblical teachings, a short statement on the Theology of the Body, and an even shorter statement of the covenant theology of the marriage act.

After quoting Humanae Vitae n. 14, we provide a list of behaviors that seek to render procreation impossible.  Included in that list are masturbation, whether mutual or solitary, and “marital sodomy, (anal sex or oral sex).”

Then we ask: “Why do we mention masturbation and marital sodomy?”  Our answer: “It’s because we listen and read.  People have told us that at one time they were practicing their own form of NFP with masturbation during the fertile time…..  We have read in the daily papers that in some parts of the United States about half of high school teenagers have experienced oral sex.

It takes no genius to realize that if couples with immoral experiences attend an NFP course and learn about abstinence during the fertile time, they may continue in their immoral behaviors unless the NFP course teaches such behavior is immoral.  Chaste abstinence is the pregnancy-avoiding “method” of true systematic NFP.”

What we teach is more than what is in most of the other NFP programs.  Unfortunately, most say nothing about morality and religion.  It is just non-contraceptive birth control. Some do not include Church teaching because they believe the method they teach stands on its own merits as a method of birth control.   Maybe in the early 1960s that was true.  But in today’s culture, chaste abstinence must be taught.

Ecological Breastfeeding and Natural Child Spacing

Background: Breastfeeding mothers experience widely different durations of breastfeeding infertility. Some have a first ovulation by three months; others one or two years later. Research studies, both prospective and retrospective, were reviewed to determine if breastfeeding patterns affect the duration of breastfeeding infertility. Studies from the 1940s up to the 21stth century show that only frequent suckling provides a significant delay of fertility. The type called ecological breastfeeding provides, on average, 14 to 15 months of breastfeeding infertility.

Conclusion: Breastfeeding types need to be defined. The Church should promote and teach ecological breastfeeding as a desirable option for natural family planning. Eco-breastfeeding involves no abstinence, offers many benefits to mother and baby, is ecologically sound, and provides extended natural infertility. God does have a natural plan for spacing babies.

Let’s start with a simple question. Does God Himself have a plan for the natural spacing of babies through breastfeeding? In other words, has God Himself created woman in such a way that the suckling of her infant at her breasts will delay the return of her fertility to produce a natural spacing of births? The answer is YES, but only IF the breastfeeding involves frequent and unrestricted nursing. This natural spacing of babies is provided without sexual abstinence.

Every woman and every man have a God-given right to learn the wonderful health benefits that God has built into the breastfeeding relationship and how these are maximized through ecological breastfeeding.  Ecological breastfeeding offers many benefits to both mother and baby, even years later after the breastfeeding has ceased. In the NFP International user’s manual, Natural Family Planning: The Complete Approach, you will find a list of 21 very specific health advantages for babies plus another six general advantages such as fewer sick days and higher scores on cognitive and IQ tests at school age. You will also find two lists of advantages for breastfeeding mothers.

When couples realize the benefits of mother-baby togetherness, this can influence some of the decisions they make. To afford living on one income after the first baby comes, they may decide to live in a lower priced house and to buy less expensive furniture.  No one can force such decisions, but if they want to do what is best for their children, many well informed couples might order their priorities accordingly.

What students are saying about the NFPI Home Study Course

Here are some comments from people who have recently taken the NFPI Home Study Course:

We had never heard of ecological breastfeeding before this. We didn’t know you could space children/extend infertility this way. We also learned a lot about the church teachings.

This course has been extremely informative and thorough in the information it provides as well as helpful in providing steps on how to incorporate what we have learned into our lives.

We have gained a completely new outlook on childbearing and child rearing. It is much more beautiful than expected.

While we completed the course, we were able to learn more about the natural signs and timings that we need to practice when our marriage begins. Also interesting to see how much our faith plays in the process of trying to conceive. [T]he charting helped as the temperature and texture test show so much about where my body is in the ovulation process.

This course has been extremely informative and thorough in the information it provides as well as helpful in providing steps on how to incorporate what we have learned into our lives.

This course was extremely thorough and informative. I appreciated how in depth the authors went in on the various Phases and Rules to ensure complete and total understanding. The mid-chapter examples of charting were helpful to grasp the concept of charting. My fiancé and I also resonated with the Catholic explanations and excerpts from different Popes on the importance of NFP and the dangers of immoral practices and different contraceptives.  

I prefer working at my own pace and on my own time, and this course allowed me to do so. [Also, we benefited from taking this course by] learning how to chart cycles properly [and] new perspectives on the role of the marriage act and children, especially thanks to the testimonials.

[The course] has taught me a lot about what the Catholic Church believes about childbirth and beginning a family. It has also taught me a lot about my own body.

It was nice to learn how the church handles family planning and [we] look forward to implementing this in our marriage.

We really enjoyed the honesty and transparency in this manual and the clear, thorough explanations, all while retaining the Catholic foundation. I have learned so much more about my cycles, added new terminology to my arsenal, and feel more confident in interpretations. Thank you so much for this amazing program! We learned so much.

Morality and the Right to Know

I think we do a disservice to anyone interested in NFP if we avoid Catholic teaching on this topic.  You do not have to present a “theology of the body.”  It may be helpful to remember that when the Pope wrote his Letter to Families in 1994, ten years after he completed his Theology of the Body lectures, he did NOT suggest to his intended audience of ordinary laity that they study his 129 lectures. Instead he urged them to remember that the marriage act ought to be a renewal of their marriage covenant (section 12).  He also reminded them that marriage is for family.

Basic Catholic teaching is simple and makes good sense.  Every human person, not just Catholics, has a God-given right to learn it.  The right kind of NFP course provides an excellent way to share this part of the truth.

Further, couples have a God-given right to know all the common signs of fertility. They should not have to take another course – at more time and more expense – to find out about the value of the temperature or the mucus or the cervix.

With regard to use-effectiveness, it is my understanding that comparative studies show that mucus plus temps has a higher effectiveness than mucus-only. The temperature sign is extremely helpful to the couple using natural family planning.

Natural Family Planning Manual

What others have said about the NFPI manual.

Great book. Super helpful. Thank you so much for offering a downloadable version, was what I needed right at that moment! …although, next time I think I’ll get the hardbound, easier to read and share. ????

My fiancee would like to use NFP once we are married, and your downloadable manual has already been a huge help to us. We found the manual thorough yet easy to understand, and appreciate the inclusion of the subjects of morality and theology.

The NFP manual I downloaded off your website is so easy to follow.  My husband and I have been using an IUD for the last six years after the birth of our second child.  We had tried NFP at the beginning of our marriage, but were disappointed with the little support we received when trying to learn NFP.  We were introduced to the Billings Ovulation Method through our Diocese and were not even aware that the Sympto-Thermal Method existed.  We got pregnant 4 months into our marriage and didn’t even finish the 3rd class. While our little bundle of joy came to us sooner than we had planned we accepted her with great joy!!! However, because of a lack of understanding of the basic tenants of our Catholic faith, we had fallen away. My husband and I, by the grace of God, have recently come back into the Catholic faith and are excited to fully participate!

I appreciate this manual so much! I have obviously been living in my body my whole life and somehow this manual has made my body seem like a whole new world of wonderful functions that God planned as only God can. The biology and theology included is immensely helpful! I see how God really did think of everything and that His plan is perfect. It makes me feel like I really am part of a bigger plan and that’s a really good feeling!

Excellent manual! Thank you so much for providing this manual online and at such a reasonable cost.

I used the NFP method once before and it worked well. I am looking forward to using it again as a form of natural birth control. Thank you so much for offering the manual free to [those] who need it!!!

When I read your manual and the covenant theology, it was like it just logically laid out exactly how I felt about the issue of birth control and what I had felt God speaking to me, but couldn’t explain. My husband read about one page of your manual, and that was it. We are never using birth control again. He understands that it is unbiblical and ethically wrong, and, just like that, my 3-year prayer is answered. I can’t thank you enough for what you do, and I will continue to help you get the word out about NFP and God’s plan for sexuality in marriages.

Natural Family Planning: The Complete Approach ought to be mandatory training for every couple who wants to get married in the Catholic Church. There is a wealth of information here that Catholics simply do not know about. I try to get information about Natural Family Planning International out to as many people as possible. This site is invaluable. Over and over I see people talking about NFP without eco-breastfeeding or proper sexual morality. Everyone (Catholic or not) needs to hear about this. Thank you once again for all of your wonderful work.

Thank you for putting the manual out there.   I’m tired of trying to remember to dig for the book when the charting is not perfectly “normal”. Now with [an e-copy] there will be no excuses! My husband and I wrestled with the issue of NFP for 20 years of marriage.  I am happy to say that now that we have both decided on an unswerving course of obedience to the Church’s teachings, the blessings have become so apparent within our marriage.

                                           A Reply to Criticism of Natural Family Planning

A few years ago, we learned about a magazine article that was quite critical of several aspects of the NFP movement. Because some of that criticism is still going on, I think it might be helpful to review it.

First, any criticism of the NFP movement in general needs to distinguish between the different NFP providers and what method or systems they teach and what they do not teach. Research clearly shows that mothers who practice Ecological Breastfeeding will experience 14 to 15 months of breastfeeding amenorrhea, the absence of periods due to breastfeeding. This truly is God’s own plan for spacing babies. Is it not a serious omission not to teach God’s own plan for spacing babies? Unfortunately, NFP International is the only NFP Provider that teaches Ecological Breastfeeding.

Furthermore, the arithmetic in the article was faulty. Without ecological breastfeeding and without any systematic NFP, the fertile couple who marry in their early twenties and do not practice contraception will have 18 to 20 children, not 8 to 10 as the article stated. I can remember very well in the early Sixties the 30 year-old mother with seven children asking me, as the parish lay evangelist, what they were supposed to do for the next 15 years of her fertility. She already had bulging varicose veins. At the time I could only mumble something about calendar rhythm, and I didn’t know much about that.

Young couples have a right to learn the full story which includes Humanae Vitae and its call to generosity and the ordinary obligation to do what is best for your children (see HV 10-16). That certainly includes ecological breastfeeding and all the signs of fertility so that they can exercise their right to make an informed decision. It also includes Catholic teaching on marital chastity so that “NFP” couples do not delude themselves into thinking that oral sodomy and mutual masturbation during the fertile time are morally permissible alternatives to the marriage act.

Young readers, I suggest you go to the NFPI website ( and click on Your Right to Know and then NFP Articles. Then explore and enjoy.

A Natural Form of Family Planning and Child Rearing

“Attention should be given to the positive benefits of breastfeeding for nourishment and disease prevention in infants as well as for maternal bonding and birth spacing”. – St. John Paul II, Address to International Conference on Population and Development, March 18, 1994

 Does breastfeeding space babies?  You bet it does.  Here is what mothers are saying!

“This is the only method of child spacing that appeals to my husband and me in every possible way.  Myself, I look for simpler answers—ones that women in non-technological societies might discover—and in breastfeeding I found it.”

“I thank you for the positive effect you’ve had on my mothering skills.  I nursed my first baby for 4 months and quit because of the inconvenience.  I nursed my second baby for 22 months because it was so very convenient.”

“My children are spaced three years apart due to ecological breastfeeding.”

And a breastfeeding Jewish mother says: “I am so thrilled with G-d’s amazing natural form of child spacing that benefits everyone in the most wonderful of ways.”

I encourage everyone to do what they can to promote this natural way of spacing babies.

Sheila Kippley, author of “Breastfeeding and Catholic Motherhood”, “The Seven Standards of Ecological Breastfeeding”, and “Breastfeeding and Natural Child Spacing”


                                                                         January 2023 Newsletter

One NFP instructor said:  The philosophy of the mucus-only method she taught “is that every woman is entitled to the knowledge of her fertility, so religion is not a part of the instruction in this method” even though the founders of the method were Catholic.   Below is John’s response.

John:  Even more important than every woman’s right to understand her fertility is her right to know God’s plan for the proper use of her sexuality.  The Great Commission of the Lord Jesus at his Ascension called for the apostles and their successors and co-workers to tell the Good News to the entire world, and to teach everything that he had commanded them.  Chapter 10 in St. Paul’s Letter to the Romans is highly applicable to the message of marital chastity.  To paraphrase, How can people be saved unless they believe and act properly, and how can they believe unless someone tells them…?

The Church is in a crisis today, and much of the problem is that too many Church leaders have treated the teaching of Humanae Vitae with benign neglect. At the same time, the leaders of the Church today are calling for a New Evangelization in which Catholics and others will become aware that it is Jesus Himself who is the Author of the teachings of the Church.

The subject matter of the NFP movement is at the heart of the sexuality crisis in the world, and a biology-only approach is no longer sufficient, if it ever was.  Participation in the NFP movement is a privilege, and it is also a call to exercise the New Evangelization.   This is not the time to hide under a bushel basket the very light that leads us.

Everyone has a God-given right to know that each and every act of sexual intercourse is intended by God to be exclusively a marriage act between heterosexual spouses married to each other.  Everyone has a right to know that the marriage act ought to reaffirm the commitment and caring love of the original marriage covenant.

Everyone has a God-given right to know about Ecological Breastfeeding, the kind of breastfeeding that really does provide a natural, abstinence-free, spacing of babies.

Everyone has a God-given right to know all the common, easily taught and detected signs of fertility and infertility.

And everyone has a right and a need to know that the Lord Jesus has given us a visible and tangible way of knowing the truth about the meaning of love and sexuality, namely, the Catholic Church led by the guidance of the Holy Spirit, a guidance promised repeatedly at the Last Supper. That’s part of the New Evangelization to which all Catholics are called.
