Oo mama, totally normal yan especially kung exclusively breastfed ang baby mo, ang yellow, seedy poop is actually a good sign na kumukuha siya ng milk properly! Kung sobrang dami ng bubbles lang at parang explosive, pwede ring lactose overload lang, kaya try mo mag-focus sa isang side lang per feeding para mas matapas niya ang hindmilk na mas puno ng fat. Pero since worried ka na, better check with your pedia to be sure, especially kung may other symptoms like hindi kumakain well o sobrang fussy siya, mas mapapahinga ka lang ng isip mo kapag nalaman mo exactly kung ano! Ang one of my mum friends din had the same worry kaya tinawagan lang niya agad ang clinic, at sabi ng doc totally fine lang hehe.
