Sitter in Sterling, Virginia

Hello Mamas, I know this is unconventional, but am sure there's a mom in my predicament out there. My daughter will be 4yrs old in 2 months. She goes to daycare all week but is home from 3pm with me. The only other child she plays with at daycare is a boy and a 2 little babies, so they don't get to do girly stuff. Am wondering if there is a mom out there with another little girl to play with her. Since am home all afternoon, am offering to babysit your daughter for FREE while the 2 play...I don't drive so I can't take them anywhere. There us a small playground in my neighborhood they can play at on a nice sunny warm day. Anyway, text or call me if interested. We can swap on days that I can't have them.  I live 5 minutes of Sterling Shopping Mall (Safeway )
