a little bit worried

if baby doesnt have any other red flags like, blue skin, vomitting, lesser urination, diarrhoea, should be fine. If the feeding is increasing or same should be okay. Kiv and if you feel its really weird, baby is lethargic, just bring to PD. better be safe then sorry

Yes this is very normal! And it is good that baby sleeps a lot for their growth in the first few months.

You’re very lucky! As long baby is growing well, it’s fine.
