Ay nako, nangyari na rin yan sa kaibigan ko! Don't worry, kung hindi umiyak si baby, chances are okay lang siya, sometimes they're tougher than we think. Ang safest talaga ay i-burp siya habang upright, over your shoulder with head support, or sitting up on your lap habang hinahawakan mo ang chin at back ng neck niya, tapos slow rock lang. A few of us try to keep baby upright for like 15, 20 minutes after feeding din para sure na nag-release ng air, at honestly, hindi lahat ng feeds may burp, so kung walang sound, totally normal na. Next time lang, maybe burp siya bago lumipat ng position to avoid the tumble, but since wala siyang reaction, siguro all good na. Worth checking with your pedia just para sa peace of mind mo, lalo na kung repeated na, okay? You're doing great na!
