Hi. DD is 11 months has been a pretty unpredictable sleeper but not horrendous.Slept all night about 2 months but regressed about 4 months,had recently settled down and slept well over xmas but last Sunday she woke up all night took ages to settle (shush pat and a bit of pu/pd like we have always done) However,even tho she seems to be asleep-heavy breathing,laying still etc,when i leave the room its as if she knows and sits up and starts screaming. I left so quietly its as if she senses im not there. It takes ages to get her off to sleep and then she wakes again a few hrs later.
Im guessing this is separation anxiety but what do i do? I wouldnt mind her coming in with us but its only a double bed and also it doesnt seem to work with her when ive tried in the past she cries more 
Any suggestions?Im sure others have experienced this.
Im going to try and sleep in a bit but will be back tomorrow for the solutions
Heeeeeeelp.
