For the past couple of months, our two year old has been covering her face (her whole head, actually) with a blanket whenever she sleeps. At night we usually go in after she has fallen asleep and pull it down to her neck. During her naps we don't want to disturb her, so when she wakes up from her nap her face is bright red and her hair is wet (with sweat) like she just had a bath. It's not like she just rests the blanket on her head - she more wraps her head in the blanket.
At first she was using her "blankie" which has a satin side - I was really worried that she would suffocate so we told her not to cover her face or we would take her blankie away. We ended up taking her blankie away but she just started using the blanket/bedspread on her bed. We can't take that away because we live up north and it will be getting very cold at night.
We tried giving her a very small (maybe 6 inch by 6 inch) thin blanket that she could put on her face but she won't use that. We have tried giving her one of those quilts that has a lot of holes in it, but she won't use that either.
We have asked her why she does it but she just says "because".
We tell her every night before bed not to cover her face, but when we go in to check on her, the blanket is wrapped around her head. Sometimes when we try to pull it down she wakes up and puts it back on.
Should I be concerned that she is covering her face? I worry about her suffocating or getting overheated. It is very hard to reason with a two year old. We even tried telling her we would take a toy away from her if she covered her face, but when we check on her later, her face is covered.
We can't get her to stop covering her face - the only thing left that I can think of is to take away all of her sheets and blankets on her bed - but that isn't really an option because of the cold weather.
I'm out of ideas so I am hoping someone here can think of something. Or maybe I'm just over-reacting and I should let her do this?
Thanks in advance!
