Ay, normal lang yan sa age na yun, anak ko din ganyan before! Usually it's because they're still learning to chew properly or kumain ng mabilis, or sometimes may sensitive tummy pa lang sila sa certain foods, kahit healthy food pa. A few of us moms notice din na pag excited sila kumain or pag maraming texture sa pagkain, mas prone sila mag-vomit. But kung frequent na talaga or may blood, or if baby looks sick, better check with the pedia para sure lang, okay?
