Tax question about mileage

Hi, I am wondering if I can write off the mileage to take FD to/from her visits? They are court-ordered and it's about a 25 mile round trip from our house, so it will add up to be a significant number of miles. Also, any other things I should be thinking of writing off or keeping records of? We've had FD since last March, so we're well over the 6 month mark. Also, we paid over $4500 out of pocket for preschool/childcare. I do plan to write that off. We are not in this for the money, but our out of pocket expenses do exceed the stipend, so it would be helpful to write off whatever we can. Thanks in advance. I did search the boards for tax info, but some of it is old and I know some things have changed and I'm a little short on time these days for some cute little reason. :D
