Hello

My daughter turned 3 weeks old yesterday and for the past two days she has been really sleepy, sleeping through feedings at night, like 3-4 hours and falling asleep while nursing & refusing to wake up to eat more.
I'm not sure if this has anything to do with a growth spurt of if its just normal. I try waking her up but it takes some convincing. I just want some advice, especially at night when she's asleep. Should I wake a sleeping baby to eat if she's sleeping more hours?
Pediatrician says she's great & gaining weight as well as having lots of wet & dirty diapers. Any help please- I know babies can get lethargic?
Re: Lethargic? FTM question?
Good luck, and I hope she is just being stubborn and is not lethargic.
