Hi mommies. Recently I switched my baby from Enfamil 1 to Enfamil 2. For two weeks her poo Will always be hard and she will have a hard time squeezing the poo out. At first I tot maybe her solids is causing the poo to be hard but I am giving her the same food as last time with veggies and fruits . Suspect it is the no 2 milk powder, anyone has same problem?
