My son is 10 years old . He has autism , adhd and extremely severe challenging behaviours . He is 2:1 at all times other than with me ( I’m a single parent ) . He pulls out clumps of my hair , bites and pushes me around . He is the same at school ( SEN school ) . He can also be lovely but the impulsivity means he can flick like a switch. I’ve been asked to consider residential for a while now by professionals but now am considering it . It breaks me thinking about it . He is also unpredictable in public places which causes problems .
