Mama, I totally understand, nakikita mo talaga kung gutom ang baby mo! But honestly, with a 3-day-old, importante talaga na makipag-coordinate muna sa pediatrician or sa midwife mo about feeding amounts, kasi bawat baby is different and they'll know best what's right for your little one.
A few of my mum friends nag-share na their doctors adjusted feeding amounts based sa baby's weight at sucking pattern, so it's really best to get that professional check-up muna before making changes. Hindi ito something to overthink, one quick call or visit lang, at clear ka na sa exact amounts para sa peace of mind mo. You're doing great, mama!
