Hi all, I have a 19 day old and for the last 4-5 nights like clockwork wakes 12pm-2am and 5am-7am. Starts with normal nappy change and feed for 30 mins starts falling asleep and all of a sudden eyes wide open and extremely fussing bobbing head and hitting and crying. Can tell she is so tired but resisting? Any advice please? She is breastfed and no issues in the day.
