I have a 6wk old baby girl and she is feeding well during the day and is on a basic schedule. However, at the first overnight feeding (usually around 2am), I am unable to get her to nurse fully. She does one side and falls asleep so hard I am unable to wake her to finish. This leads to her waking every 1.5 hrs thereafter. I have tried changing her, taking her down to just her diaper, talking/singing to her, playing with her feet (which she hates usually), turning on the lights, and even some cool water on the face. Does anyone have any creative suggestions as to how to wake her so she has a full feeding and sleeps better?
