Now it's August I guess most our babies are here now....

Those of you who formula feed how many times are your babies pooping a day? At around 1 week old??

My baby had his meconium.. a day or 2 of yellow/mustard poops.. and hasn't done an other for nearly 48 hours.. well around 12 hours ago there was the tiniest bit that looked like it came out with wind but that's been it.. how much longer until I need to call for help?

I must add... he's fine every other way.. feeds,well.. sleeps well... not fussy or crying.. so no signs of pain or constipation other than there being no poop

Any advice? Anyone else babies the same?
