Hi Shelagh,
You might want to read another thread on the Baby forum where 2 of us have been having problems getting our little ones to sleep too, so at least you know your'e not the only one. The only thing i can suggest is a baby sleeping bag so you don't need to worry about covers and her getting tangled up as it will move with her when she wiggles - the other thing is putting her in her own room with a black out blind - try and do that with at least one of her daytime naps too, as it helped with Tara.
The other thing is if you have to go to her in the night, no eye contact or talking. I found that being firm with Tara and repeating the same thing every night has improved. She is now settling herself at 20.00 pm with me in the room putting her dummy back in, even when she is crying - she eventually does a big sigh, gives in and goes to sleep - took me an hour to start with -have got it down to 10 mins now. i don't pick up her up, just keep putting the dummy in, and she can see me but i am not talking or giving eye contact.
I think with Tara is that she understands it is bed time but doesn't want to sleep without me, but because i am in the room she eventually relaxes and goes to sleep - once she is asleep that is her until 07.00 am.
I understand how frustating it is as you need a rest too - it is hard work having them all day and you need a break.
I couldn't do controlled crying, and i read Gina Fords contented baby book, some bits i found useful, but others just didn't work, but i think a bit of tough love will hopefully get the results you and she deserve - your daughter a nice sleep, and you a break in the evening and an undisturbed night of sleep.
Good luck with it Shelagh and let us know how you get on.
