Alamak, constipation kat anak kecil memang bikin parents stress! Bisa jadi formula milk memang jadi culprit, a few of us noticed our babies poop jadi lama dan keras lepas tukar brand. Tapi boleh juga sebab dia dah makan solid food yang tak cukup air, atau just his system adjusting. I'd suggest dulu check dengan doctor paediatric kau to make sure tak ada masalah lain, then barulah decide nak tukar formula or adjust diet. In the meantime, minum air banyak-banyak lah, and if you're considering formula switch, ada banyak brands out there but best discuss dengan doctor yang kenal baby mu better. Sabar ye, macam-macam phase anak ni!
