Dd had a feed at 3.45am and then we had a cople of hours of fussing, wind, crying and not going back to sleep. Dh brought her downstairs and she finally dropped off about 6am. I'm now up and would or normally have fed her an hour ago. She's still conked out. Do I wake her to feed or leave her to sleep a bit longer? She is starting to stir a bit but eyes still closed.
