How old are your children, zzzzz? My DS1 has severe OCD. He's 14, but he's had it since he was at least nine, if not before. Whilst I was waiting for help from CAMHS, I worked through this book with him. It helped him, but it also helped me understand OCD better.
This was also really helpful and good for very young children.
The only thing that worked for DS1 was CBT with ERP (Exposure Response Prevention). CBT on its own didn't have the same impact. Might be worth bearing in mind if the OCD-type behaviour continues.
It is very stressful living with someone with OCD. You have my sympathy.
toffee thanks I will look at your links. Ds1 is eight he has needed to touch things, go through doors in particular order etc for a long time. The touching is far more overtly anxiety driven. Dd3 is 6. I feel out of my depth. It is all so illogical.
all. I'm sorry to be so bleurgh. I don't think ds1 can access any sort of "talking" therapy. In some ways I find his behaviour less worrying because he has always been a puzzle. Dd3 is coming off some mind bending meds and I need to make myself be calmer and wait.
