In this day and age, I don't think you can't worry about too many bumps and bruises raising eyebrows. My 5 yo is going through a very clumsy stage and recently had a goose egg on her forehead, a bruise on her cheek and some bruises on her shoulder/arm -- all from running into door facings, school chairs, etc., as she rushed from one thing to another. I'd probably raise my eyebrows, too, if I saw another kiddo so banged up.

Definitely look into faith-based foster-care agencies. There are plenty out there. We went with the state agency -- church affiliation was considered to be a plus because of the support systems that you typically develop there.
