I'm looking for opinions, one of my colleagues' daughters is going to be babysitting my 1 year old for a few hours (2 2 1/2 hours) on a Saturday evening (around 6-8ish). She's 16, super responsible and keen to do it. I'm wondering what the going rate is for babysitting? I don't want to under pay her at all! And since that's awkward timing, so I leave her some dinner? Like a pizza or something? What's the done thing?
