We have been using the fold over cuffs/mittens in the wondersuits for our DD since using a sleeping bag.
She is 6months and I have gone to buy her size 0 ones but no more cuffs!
How did you transition from not having there hands tucked away? She is a nightmare to get to sleep otherwise, pulls the dummy out, wants to play etc. She doesnt cry or anything but just wants to keep playing. Plus she touches her face a lot when going off to sleep so also worried about scratching.
