Ok Im not sure what to do, im starting to have sleepless nights and I dont like it!! I need help!!

I have been putting DD to bed in her bassinet next to our bed every night since she was born (with the exception of the early days where we were co-sleeping quite a bit).
I normally wrap her up and tuck her in with a blanket and rock the bassinet to help her get to sleep, everything has been going fine with that up until she discovered her hands a week ago and has decided she loves sucking on them. Now it is a struggle to wrap her up, shes fighting to get her hands out, it doesnt matter how tight i do it she just grunts, groans and whinges until i give in and unwrap them. The problem with that is then she cant sleep cos her hands are waving around or shes too busy sucking on them.. she will start drifting off with them on her chest and will startle when she relaxes and they start falling down beside her. This goes on until she starts grizzling cos she really just wants to go to sleep!

Last night i managed to wrap her and she went to sleep fairly easy only to wake up a few hrs later trying to get her hands out, i fed her and tried to wrap her back up and put her to bed. Well there was no way that was going to happen! So i left her arms out, well for the next couple hrs i listened to her sucking and grizzling until she started crying for another feed. I fed her and just couldnt be bothered going thru it all again so i let her sleep on me. Which meant i didnt sleep very well cos i was worried about smothering her (im paranoid cos i have heard too many bad stories lately!).

I am very very tempted to start sleeping her on her tummy cos she sleeps so well like that during the day (im always checking on her every 10 mins!) but i am just too scared to do it during the night! It is drummed into everyones heads so much these days about how it contributes to sids etc that i am just too worried that if i do it something will happen to her, and i will never forgive myself.

What do i do!!!! Would u/do u/did u.. sleep ur baby on its tummy during the night?? I probably wldnt even get any more sleep then i am now cos i wld be constantly checking on her!
I dont know.... im starting to dread night times and her waking up for feeds cos i just know its going to be such a struggle, it sux cos she was so good at night, she never cried.. and she was starting to sleep in 4-7 hr blocks! It feels like ive messed her up cos i have always wrapped her or held her, ive never let her just sleep on her back with her arms by her side or up next to her head or anything.

I am just about to go and wake her up cos dh thought he wld do me a favour and put her to bed tonight, but the silly bugger put her to sleep on her tummy in her cot in her own room! I cant leave her there!!!

Any advice wld be muchly appreciated!! Thankyou!
