Dd is 4 weeks old and EBF- a big girl 10lb 4 now and born at 8lb 2. Now I never want to wake a sleeping baby especially a big thriving one but yesterday she slept from 230pm until 8pm and then was very fussy until 1am. She then slept until 5am fed and back to sleep by 6 - she is still asleep. I am very worried about this change in schedule and was wondering - should I wake her to protect my supply!
