Aw, ang bilis ng time! Nung 3 weeks old ang aming LO, around 2-3 oz per feeding lang talaga, every 2-3 hours, pero very variable pa because adjusting pa siya sa formula. Bawat baby talaga ay different, some of my mum friends had babies na mas gutom agad, kaya mas marami na sila drank, so better to follow your LO's cues at don't force if full na siya. Since feeding amounts at milk intake are really individual, best to check with your pedia para ma-confirm kung sapat na ba ang intake ng baby mo at umuusog siya ng maayos.
