DS7 rejects his bed and has done for years. He slept in his own room from birth until last summer but from about age 4 would sleep on the floor instead of his bed. He currently shares with DS4 and they have the IKEA Kura bed which is a high sleeper with a mattress underneath. DS4 on top and DS7 on the bottom. I was hoping him being low down would mean he would sleep on his mattress but he still chooses the floor. He's currently on a camping roll mat with a duvet on top and then sleeps in a sleeping bag! He's being assessed for ASD so maybe it's a sensory thing? Anyway their bedroom isn't massive and it seems silly to have this mattress taking up a load of space but not being used! Would it be crazy to turn it into a reading area or something else and ditch the mattress? I know a lack of a bed can be a red flag for social services if he mentions it at school and don't want to end up in trouble.
