Oo, common yan sa babies especially pag nakatulog na pagkatapos ng milk! A few of us noticed the same thing, parang mas sensitive ang kanilang airway when they're lying down after drinking, kaya sobrang easy mag-trigger ng cough. Try mo na mag-burp ng mahabang panahon after milk bago mo ilatag, at kung pwede, panatilihin syang slightly elevated for a bit after feeding para hindi agad umupo ang milk sa throat. But kung persistent yung ubo or concerned ka na, mas better mag-check sa pedia para ma-rule out kung may ibang cause or if baby needs any adjustment sa feeding position!
