Oo, totally normal yan lalo na sa first few months! A lot of us moms actually observe na kapag nagdede ang baby, tumatae agad, it's called the gastrocolic reflex, parang automatic response ng sistema nila. Basta kung okay ang dumi (yellowish, may seeds na parang cottage cheese kung breastfed), wag mag-alala, sign lang yan na kumakain siya nang maayos at ang digestive system niya ay gumagana well.
