Amelie (5 months) was doing really well at getting off to sleep on her own recently- we would wrap her when we saw her tired signs, pop in the dummy and off to sleep she went!

But, since she has started rolling (back to front only and then getting stuck on tummy and crying to be turned back over) I have found her all over the place in her cot. Worse than that, she has occasionally had her wrap twisted and I'm worried about it going over her head and suffocating her. So, with the advice of a Child and Youth Health nurse, we have stopped wrapping. However, this means that she now rolls over when trying to go to sleep, gets upset and cries. I am almost sure that the rolling is an involuntary thing. No matter how tight I tuck the sheets in, she still does it. Sleeping bags don't help, as it seems to be having her arms out that bothers her. We have been persisting with this for a couple of weeks now, and it invariably ends up with me needing to sit next to her cot, restraining her arms until she drifts off to sleep.

Any advice / gadgets that might be able to help me temporarily restrain her arms until she gets to sleep, but not while she is asleep?
