Ahhh constipation memang common dengan formula, especially kalau formula tu tak suit. Tiga hari tanpa berak tu boleh jadi concerning, better check with your pediatrician cepat-cepat untuk make sure baby okay and get proper advice on formula atau diet adjustment, sebab sometimes kena tukar formula brand or add supplements. A few of my mum friends, their babies got gassy and constipated with certain formulas, then once tukar, okay je, so it's worth exploring with the doctor. Good thing baby masih happy and feeding well, but jangan delay the check-up, k!
