progesterone released during pregnancy relaxes the intestinal muscles, which slows down your bowel movements.
Whereas multiple bowel movements a day are normal for many breastfed infants, formula babies may expel less often.
Breastfed babies generally have more daily bowel movements than formula fed babies, but don't be surprised if your baby poops several times one day and then not at all the next no matter what type of milk she is eating.
In the first few weeks after a baby is born, breastfed babies usually have several bowel movements a day.
After those first few weeks have passed, however, you may worry because your baby's bowel movements are only occurring every few days.
