My dd (17) still sleeps with her blanket and literally cannot be without it at night, she has had it since she was born but just won’t give it up. She is mature for her age apart from this. When I looked in on her just now she had it over her face just like she was 4 years old again, she used to have a thing about it keeping her safe while she was asleep. She will hopefully be off to uni in September and I’m very worried about this, she can’t exactly take it with her can she? So is this weird or am I just overreacting?
