Hi,
My 4yo used comforter blanket as a baby to get to sleep and when he was upset he started to seek these out. Around age 2 we made them a bedtime only item and weaned him off entirely a few months later. However after 6 months of no comfort blanket, he discovered, rather proudly, that he could just suck his duvet. Help. Thought he might grow out of it but he still rams it into his mouth every night, is very resistant to me talking him out of it. He's not stressed out or anything when he goes for it, just tired. Sometimes he will try chew a blanket if we have one out for keeping cosy in winter, but he knows he's not supposed to so he tries to be sly. Again, not stressed, usually just when he has a bit of screen time. I can handle the day time part easily but I'm at a loss as to what I do about his chewing the covers at night....
