Hi mama! Kung ang first poop ay medyo matigas pero ang second one ay normal na, usually okay lang yan, sometimes babies just have varied poops throughout the day, lalo na if nag-adjust sila sa new foods o formula. That said, kung notice mo siyang uncomfortable, or if the hard poop happens again frequently, better check with your pedia para ma-rule out any constipation concerns, hindi na rin masakit magpa-consult lang para peace of mind mo, di ba?
