I'm starting to worry a litlte bit about one of my girls. She sleeps really well during the night - BF'd at about 8 and goes right to bed, sleeps until I wake her around 2 or 3 a.m. and goes back to sleep, wakes around 8 a.m. for the day. I use the phrase "wakes for the day" very loosely, she is not awake much at all these days. She eats every 3 hours, sometimes I have to wake her to eat and if I do, I let her go only until it's been 3.5 hours since she ate last. So she's awake long enough to eat, most times going right back to sleep after. She might be awake for a total of 2 hours more during the day, that's in addition to being awake for like 20 minute per feeding. I can't help but compare her to her sister who is still waking every 3 hours during the night and is awake for about an hour after almost each feeding during the day. Anyone else's 8 week old sleeping a lot??
