Breastfeeding can
decrease fertility, regardless of the frequency of breastfeeding or
whether mom’s period has returned. Exclusive breastfeeding (by itself) is
98-99.5% effective in decreasing fertility
as long as all of the following conditions
are met:
1.Your baby is less than six months old
2.
Your menstrual periods have not yet returned.
Breastfeeding frequency
and total amount of time spent breastfeeding
per 24 hours are the strongest factors leading to the return of fertility:
a mother is more likely to see the return of fertility if baby's nursing
frequency and/or duration is reduced, particularly if the change is
abrupt. In some populations, research has shown that breastfeeding in the
night slows the return to fertility. Once
baby starts solids (if mom's cycles have not returned), the natural period
of infertility may be prolonged by breastfeeding before offering solids,
starting solids gradually, and not restricting nursing.
You can achieve higher
effectiveness in decreasing fertility by practicing
ecological breastfeeding:
keeping baby close
breastfeeding on cue
(day and night)
using breastfeeding to
comfort your baby.
The transition to full
fertility
It is not uncommon for
breastfeeding mothers to report cyclical cramping or PMS-type symptoms -
symptoms of an oncoming period without the period - for weeks or even
months before their period returns. When this happens, the body is
probably "gearing up" for the return of menstruation, but breastfeeding is
still delaying the return of fertility.
Do I need to stop
breastfeeding to increase fertility?
If
you are still transitioning to full fertility (as discussed above),
breastfeeding may affect the success of implantation. Once implantation is
successful, breastfeeding should not affect a healthy pregnancy (see A New
Look at the Safety of Breastfeeding During Pregnancy for more
information).
Many
moms can conceive without deliberately changing their toddler's nursing
patterns. Changes that are more abrupt tend to bring fertility back faster
(e.g., cutting out one nursing session abruptly, rather than gradually
decreasing nursing time at that session) --even if you continue to
breastfeed a great deal-- this is why many mothers experience the
return of fertility when their child sleeps through the night or starts
solid foods. For more information, see Getting Pregnant While
Breastfeeding by Hilary Flower.
What have other mothers
done to increase their fertility without weaning?
Toni Weschler's Taking
Charge of Your Fertility is a comprehensive guide to many aspects of
fertility and includes a positive and encouraging chapter on breastfeeding
and fertility. Of course, the classic book, Breastfeeding and Natural
Child Spacing by Sheila Kippley, continues to be a valuable resource
for a clear understanding of the impact of breastfeeding on fertility.
Sometimes it takes only a slight decrease in nursing frequency to resume
ovulation and menstruation to achieve another pregnancy.
Many mothers find that
simply reducing the breastfeeding by just a small amount will bring a
return of fertility without complete weaning. If becoming pregnant with
this baby required little time, then even though you are in your late 30s,
it's possible that when your fertility returns, your chances of becoming
pregnant are very good.
