hi, my dd is 19 weeks and has started to wake roughly every 3 hours and then seems fully wide awake by about 4am and will sometimes go back down at 6ish. She goes down at 7pm which is when she seems to be tired. She was a great sleeper when first born so maybe I was just spoilt and expecting too much now. I have tried feeding her which works to a point but once she is wide awake nothing seems to! She was also happy to go down for her naps but for the last couple of weeks she has taken to only sleeping on me again and crying when i put her down. She has already got some teeth and I did initially put it down to that but there don't seem to be anymore coming through so don't think its that. Any suggestions? Thanks, Sleepless in North London
