Eh, susah la nak tentukan betul-betul sebab dari susu je sebab banyak faktor boleh affect, tapi kalau dada dia berkahak dan kurang minat minum, mesti ada something yang tak okay, worth checking with your paediatrician dulu sebelum tukar formula lagi, sebab frequent changes boleh buat perut baby confusion. A few of us tried switching back and forth dan mostly doktor suggest kita tunggu 2-3 minggu dulu kat satu formula baru sebelum judge, as baby needs time to adjust. Kalau Dutch Baby memang buat dia berak banyak sangat tu is a sign perut dia tak settle, so lagi best avoid balik. Lactogen yang sekarang okay for drinking, jadi maybe the wheezing tu separate issue, could be reflux or minor congestion (normal kat babies actually), tapi do mention it when you see the doctor, they'll listen to his chest properly.
