Bergantung lah pada baby age dan consistency, tapi usually formula fed babies punya poop yang lebih tan/brownish dan lebih padat sikit compared to breastfed babies. A few of us mums noticed our FM babies poop less frequent tapi heavier, dan ada sikit smell, that's all normal! Kalau color dia greenish or ada mucus, atau baby seem uncomfortable, better check with your pediatrician to be safe. Otherwise don't worry too much, setiap baby beza-beza aje!
