Hello. my baby is 2 months old. she is on nan ha. her poo is very smelly, green and sticky. she isnt able to push her poo out. she had been in s26 gold and nan opti pro. it is difficult for her to make poo on her own. she gets bad tummy craps?

3 different formulas in 8 short weeks is too much! Newborns and infants are still getting used to the sensations of pooping, peeing, eating and various movements. They may look like they are straining, but it is because their muscles are still not strong enough to poop without pushing. Crying is common. Pick one formula and stick to it. Talk to your pediatrician about normal infant behavior.
