Hi, I have a nearly 9 month old and he is a worm especially of a night when I put him down to sleep he wiggles around but that isn't the problem I don't mind that I can just move him back. The problem is other morning he woke me up with a loud scream i found him wrapped up in his blanket including over his face he couldn't get it off! He sleeps in a grow bag but i'm scared now to give him a blanket. Is there anything I can try? Or is a grow bag enough to keep him warm? Thanks for any tips x
