I am probably being completely paranoid but for the first time my ds is using a duvet (he is 19 months old). It is a nice heavy cotton one but doesn't mould well round the body - if you see what I mean. It is so cold tonight, even with the heating on. I have just been up to see him and he has wrapped himself in it with just the top of his head peeping out. We have just moved the duvet down a bit but I am worried he will do it again and that he will suffocate. Am I being mad?
