Ang lactose intolerance sa babies ay medyo tricky kasi mahirap malaman agad, pero usually makikita mo if persistent ang diarrhea, bloating, or gas after feeding, one of my mum friends noticed her baby was always fussy and had greenish poop, tapos nung na-switch sila sa lactose-free formula nag-improve na. Best thing talaga is to mention these symptoms to your pedia dahil kailangan ng proper testing at guidance para ma-confirm, at para malaman din kung cow's milk allergy lang or lactose intolerance talaga, kasi iba ang treatment nila!
