DS is 21 months old, he's in a bed, but frequently wriggles out from under his quilt/blankets, and I think getting cold is contributing to his early wakening. I don't want to go back to gro bags as he gets himself out of bed in the morning and comes into our room, but was wondering if anyone had seen any warm/fleecy sleep suits that we could put him in over his pyjamas? or any other ideas?
