I need help 
Dd 6 months is not a great sleeper.
Since 8 weeks, myself and my husband have taken it in turns to bring her up to bed at 7pm while the other brings dd1
It was manageable up to a month ago where baby would have bottle ,rock to sleep and go into cot. She would generally stay there for a few hours and wake twice for feeds until the morning. All manageable.
Before she got worse she actually got better sleeping until 4am then having a bottle and sleep till 6.
It has gotten progressively worse.
We are now at the stage where she will not go in the cot( when I say cot I mean the sleepyhead in the cot)
My husband brings her up at 7pm and she sleeps on him until 9.30 won't I come up. She then co sleeps with me but basically only in my arms so it makes for a very uncomfortable night:
We have made the cot into a side car cot and she will wake 60 seconds after I roll her over.
I need her to even stay in the cot for the first couple of hours during the night as myself and my husband basically don't see each other as he is in the spare room now.
My first was an amazing sleeper and still is, I'm actually shocked at the difference between her two!
PLEASE HELP me figure out a way to make dd more comfortable in her cot!
Extra info- took sleepyhead out when we side cared ( is that a word?!) the cot
We have white noise
Naps in car seat on school run and have to put her in to bed beside me for naps as refusing to go in cot
Have used the hot water bottle trick
Have put my top in so she can smell me 🙄
She's in a gro bag
Drinks two 7 ounce bottles during the night and wakes when dd1 comes in about 6.30/6.45
Black out blind up
