i'd like to chime in too. My DD is 7 mths, and has been sleeping through the night since she was 3 mths. Her naps have always been a bit all over the place, sometimes 2 hrs, sometimes 40 minutes. She used to sleep until 630/7, but for the last month has been up at 5/530. Sometimes i feed her, and she'll go back to sleep until 6/630, but not very often. Her trouble, is she can't always stay up for 3 hrs at a time yet, and if i don't give her a cat nap, she'd be in bed at 530! I'd rather give her a cat nap and keep her up until 730/8, but then she is still up early and cranky! I don't think she is getting too much daytime sleep, if it is a bad day it can be as little as 2.5 hrs for the whole day. I am also wondering if feeding her when she wakes up is becoming accidental parenting. My friend who has a 9 mth old ds that wakes early never feeds him before 6:30 no matter when he wakes.
