Ad hoc summer childcare - any au pairs want extra hours?

[Fjgb]

Does anyone have an au pair / nanny that might be looking for a few extra hours work during the day in the summer? I need someone on an ad hoc basis that could come in and look after my son / take him to the park etc for potentially a few hours a couple of days a week whilst I join conference calls etc before I go back to work properly. He doesn't start at the childminders till September. I will usually be around but looking for someone who is good with babies as he's almost 1. I'd like to have someone regular to call on that we could also use for babysitting etc for him and my older daughter.
