We now have the full time care of our grandchildren as their mother has left them. We have just got child benefit and are about to claim child tax credit, and according to the entitledto site we should get some. DH works, I dont I get incapacity benefit. The eldest is 3 and in nursery which of course is free. If I was to put the youngest into private nursery for just one afternoon a week to give me a break, would I be able to claim this as childcare costs and get it back through CTC even though I dont work?
