Rory I have the same problem you have. Marley won't sleep at all without being wrapped like a mummy! Soon as she is free, she wakes. I tried to put her to sleep without wrapping the other day and it didn't work. She is constantly shoving her fingers in her mouth and just starts playing. As soon as I wrap her, bang, she is fast asleep. She sleeps so well, I hate the idea of disturbing her so I might leave it for another month. I have a GroBag for her which Chelsea used and loved but I don't know when she will get to go in it!!! Funny how some babies hate being wrapped and others love it. Ours obviously love it LOL!!!
