low appetite and increase sleep

Babies go through a growth spurt between sometime between 4-6 weeks old and a mental leap around 5 weeks old. During these periods they may feed/sleep more or less than usual, amongst other behavioral changes.

Yeah newborn tend to sleep more. You can try to wake him/her to feed him, if don't want then it's ok. As long as wet diapers meets the requirements & your baby don't look dehydrated, it's ok. Every baby is different. Enjoy this moment when your baby like to sleep, not gonna be forever lol

Mine yes during sleeping time he will cry and ask for milk but don't drink and sleep back... After 4-6 hours he will wake up and ask for milk to drink

Hi, It looks like a growth spurt symptom. Also every baby is different so don’t worry and gradually it will be fine

Likely growth spurt. Should return to normal soon

Maybe you can check with tHe pediatrician
