First, I'm sorry you have OCD I've had it severely and it is horrible...and well i think it is not hereditary but it might be unless she is getting things from you but the best thing to do is check it out with a doctor..
My son has it..he is 28. It was never an issue when he was growing up . Tho he never wanted to miss school and actually went an entire year without missing a day. I guess I behaved like that, .trying to keep the house in good shape..but have eased a lot since I got older, I wonder tho if it is more of what your child is exposed to as opposed to it being heredity. Maybe a talk with your child's physician on the issue could help you and your little one.
