Hay, totally understandable na you're worried, but actually normal pa yan sa ganitong age, especially if mixed fed, some babies take a few days pa lang before they establish their pooping rhythm. Pero since 6 days pa lang si baby at importante ma-monitor ang intake at output, I'd really suggest you check in with your pedia just to be sure everything's on track with feeds, kasi peace of mind talaga ang kailangan mo ngayon at hindi worry! A few of us sa circle namin worried din nito, pero after pedia clearance natulog nang maayos kami. Good luck, mama!
