DS (ASD - 5) has started independently (and obsessively) taking himself off for baths. Usually when we are busy cooking - during Xmas dinner we found him naked in the bath with water 1cm from the brim. Am mainly worried about him scalding himself / drowning although we have turned down the thermostat so hopefully the water can't get too hot. I have found an alarm on amazon you can suction to the bath and it goes off when the water reaches that level which I guess I can position near the bottom of the bath, but welcome any other ideas. I can't lock the door as kids need access to the toilet.
Am all for DS gaining self help skills but this is ridiculous.
