My 5 month old DD isn't the best sleeper the past month or so. Still getting up 2-3 times per night to eat. Usually she eats and goes right back to sleep. Well now most of the night she is just laying in her crib awake tossing and turning. And when she does fall asleep it is only for like 15-30 minutes before she wakes up again and the whole tossing/turning starts over again. She's just completely awake and doesn't seem to be able to get into that deep sleep state. I feel so bad for her because if I count up all of the short little sleeps she is getting through the night, she is probably only getting 3-4 hours total all night. I don't know how to help her and she doesn't seem to be in pain/distress. During the day she is so tired. Has this happened to anyone?
