Ds is 1wk old, we are topping up regularly with ebm as he has poss tongue tie. Doula says nor to let him gonfor longer than 3 hrs without a feed even at night. He was unsettled and hungry all morning when I let him sleep for 5 hrs the other night. Once he is feeding efficiently and not needing topups, I can just leave him to sleep till he wakes for a feed, right?
