Autistic traits

[Ali]

Hi,

I am a new member and would welcome any discussion regarding obsessional behaviour. my 17yr old son has an obsession with nappies. i can't work out why. he has been toilet trained since age 5.Has anyone else experienced anything similar?He accesses mother and baby rooms and takes nappies and puts them on. i found them in all sorts of places around his room.It causes immense stress and i can no longer trust him when we go out. I cannot accompany him in gents toilets so restricts us going out. any help appreciated. thanks. Ali
