My soon to be 8 year old son came back from his dads house tonight and told me he’s sharing a room with his sister who is dads and step mums child , sister is about 3 years old which is fine it’s only a few nights a week. However he said he sleep on just a mattress with a sleeping bag . And that previously he was on a camp bed in dads room again with a sleeping bag as he no longer could share with his younger brother as brother is autistic so needed his own space which is totally fair! Need advice on whether I should be mad about the mattress and sleeping bag . I just feel if there is room for a matress there is room for a bed and that he should have proper bedding as it should be his home aswell not just a visiting spot
