Aww macam normal je untuk 2 bulan plus, sebab babies tu mmg tidur banyak pada umur tu, biasanya 16-18 jam sehari lah. Yang penting is patern dia konsisten dan dia seem content, so your baby sounds perfectly fine actually! Personally a few of my mum friends' babies at that age also tidur 1-2 jam berjaga then tidur balik, so jangan worry sangat. Just keep monitoring if dia gaining weight well dan wet diapers okay, then you're good lah. Kalau ada doubts mmg better check with your pediatrician just to be safe!
