don't worry hon i would just leave her, its scary at first but in a few months you will look at the positions they can get themselves into while asleep and lough.

sometimes my son sleeps in the worst positions that his arms and legs look like they might just snap but if i move him in 10mins he is back to the same position again.

she is old enough now to move around in her sleep, as i said i would just let her go.
