Yes, if baby's breastfeeding, he could poop as often as after every feeding during his first six months. But it's also normal if baby's only pooping once every few days. Do keep an eye on the color and consistency, though: Breastfed babies usually poop a mustard-yellow color, but the poop could range in color from yellow to brown to green no matter how he's fed. All those colors are normal, and there's no reason to worry—as long as baby's poop isn't hard. If it's hard and pebble-like, red (could be blood), black (could be digested blood) or white (could signal a liver problem), give the pediatrician a call.
