Hayyy mama! 4 kali sehari actually normal je untuk budak umur setahun, especially kalau baru tukar susu, memang boleh affect the poop schedule, some babies kutut sikit during transition period. Sebab itu a few of my mum friends dapat constipation when switching formula, so it might take a few days to a week untuk baby adjust. Tapi if your little one okay je, happy, and tidak nampak uncomfortable, most likely dia tengah adapt with the new milk je. Kalau tetap berbeza or terlihat uncomfortable, mungkin bagus check with your paediatrician to make sure the new formula suits him okay?
