[Highland Park] babysitter on Wednesdays?

I need a babysitter for an hour on Wednesday afternoons, to hang out with my 8yo, 4yo, and 20 month old for an hour. Probably from 345-445 should do it. Very low-key, just keep an eye on them at the playground or my house or whatever, while I take my 6yo to piano lessons. Call me at 412 362 9996 or email me back.
