My DD is 11 months we've have a routine since we came home from hospital just obviously changed slightly as she got older. So now it's dinner at 5pm (usually quite a large dimmer with dessert) bath at 6pm, bottle in dark bedroom then she's usually asleep between 7-7:30pm. I am also loving with my mum at the moment, and supposed to be moving out soon but some problems have now pushed it back So it looks like it's going to be end of summer time now 
so DD is in my room.
She wakes at around midnight-1am for a bottle, sometimes she'll go til 3am but most it's about 12/1. She also wakes to come into my bed at 11am. I've tried ignoring her for this, or just placing her back laying down, nothing works but I'm fine with her sleeping with me for now, I guess she just likes the closeness and I'll try harder when she has her room.
After her bottle though most nights she's incredibly fidgety if i place her back into her cot, she wakes herself up because she ends up hitting her head off the bars, is she's in my bed she pushes her bum as high up as she can, then flops to the side, she sits up and then falls backwards, she loves from side to side, onto her stomach, onto her side, onto her back.... I don't know why she does it. To stop it I have to "spoon" hold her then she'll sleep for a bit but my atm starts to hurt so if I gently take her off my arm she starts the whole fidgetting again...
Is it something to do with the milk do you think? Should I try weaning her off it and see if that works? Or is she just a fidgety sleeper? I have PND and attending therapy, so the sleep deprivation isn't helping me also back at work, also I assume it's not good for her either. I can't do CC or crying it out because if she's crying I get really stressed out.
TIA for any help.
