This appears to be more of a general survey for anyone looking after any child, not just a disabled child.
I have filled it in, but my son is an adult,and I am a Carer for my husband too.
One thing, I gave up work as a nurse to become an unpaid Carer. I do not consider myself unemployed. I am far busier now, than ever I was when I was nursing, plus i do not get teabreaks or mealbreaks,(or even toilet breaks), uninterrupted.
