HELP! I have a 6.5 week old who is a pretty happy baby and a good sleeper, for the most part. Our bedtime routine starts at 8:45, we read books, have quiet/cuddle time, then eat at about 9:30. Last night, she ate at 9:30pm and didn't wake up until 2:30am! Then, it all started...she finished eating and I burped her and she was back in crib by 3:30 (she is a slower eater) and by 4 am, she was crying! She typically does ok if she wakes up every 3 hours, example: goes to bed at 930, up at 1230 and will fall back to sleep until 330...it's that 230 or 330 feeding that she usually doesn't like to fall back to sleep for and stay asleep. I should clarify, she will fall asleep while eating/burping, but wakes up no longer than 1 hour after i put her back in crib...help, what do we do!?
