Our children are naturally spaced just by breastfeeding (hey, that’s free too!! The wonder of it!!!). My husband and I do not use any contraception and I still had an absence of fertility for 13 months (imagine that) and did not get pregnant until 19 months postpartum.
I think that’s why God gave us breastmilk to begin with. And Pope John Paul II always insisted mothers nurse their children until at least the age of 2.
Lactational Amenorrhea Method
The lactational amenorrhea method, or LAM, is based on the ability of breastfeeding to suppress ovulation, the monthly release of an egg cell from a woman's ovary. Women can prevent pregnancies with LAM if their periods have not yet returned, and if their babies are less than six months old and exclusively or almost exclusively breastfed. With correct and consistent use, LAM is over 99 percent effective versus 98 percent effective in actual use.
"The wonder of it!!!"
As our parish priest said: "God don't make junk."
