I have to admit I do get in there pretty quick and give her a dummy and pat, just cause it's the middle of the night and i don't want her waking up the neighbourhood!
I don't know if she is hungry, it happens about 3 hours after she goes down and then she doesn't settle again properly for the night. If i feed her she might eat a bit and then settle for a couple of hours but that's it. She used to be very predictable and was slowly sleeping more and more until she hit 6 hour stretches at night, and then it all went out the window!
Generally she wakes at the same time, at 3, though last night it was earlier, but we did put her down earlier!
