6 week old formula fed. Isn't pooping, it's been over 12 hours and last time he pooped it was diarrhea. Any ideas on…

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.
