Normal ke najis begini?

Hmm, it's hard to say without seeing la, but usually when babies first switch formula, their poop does change colour and consistency for a few days, totally normal! If it's loose and watery and happening super frequently (like more than usual), or if baby seems uncomfortable or feverish, then boleh jadi cirit-birit and worth checking with the paediatrician just to be safe. A few of us mums went through this and our doctor said unless the baby is losing weight or acting unwell, usually it settles within a week or so once they adjust to the new milk.
