Eh, macam tu memang boleh jadi normal lagi, especially if baby dah on formula! Babies on formula biasa poop less frequently compared to breastfed babies, 2-3 hari sekali tak unusual. Yang penting tengok consistency (should be soft, paste-like, not hard), warna (yellowish-brown ke greenish), and kalau baby okay je, feeding well, weight gain bagus, tak ada tanda-tanda constipation seperti straining teruk or crying, then likely semua fine. Tapi kalau you're worried pasal texture or ada changes, better check with your paed just to be safe, they can give you peace of mind and confirm based on what baby actually passing.
