Hi mama! At that age, breastfed baby poop can be so different from day to day, yellowish, seedy, sometimes greenish, and anywhere from a few times a day to even just once every few days, lahat normal pa yan! Since you're a first-time mom, it might help to check with your pedia just to be sure everything's okay with feeding and baby's weight gain, pero from what you're describing, it sounds like pretty standard newborn stuff.
