my doc told me when they aren't pooping try taking their temp, a bit of vasoline. it might help things come out. also a warm bath.

it's normal for babies to go a day or two without pooping. if he is fussy and has a hard belly do some belly exercises/ belly rub

Get him some baby prune juice from the store, they have individual servings and it's safe for him to have. I always have it to my son when he was little.
