Question: how long is it ok for a baby to not poop?
Answer: Breastfed babies, especially if they have not started solid foods, can easily go two weeks without a poopy diaper once they are 2-3 months old. Breastmilk is exactly what your baby needs, and so there is little waste product left for the baby to poop out. Exclusively breastfed babies are almost never constipated.
