AIBU regarding Au Pair?

[kimlek]

I've been reading about Au Pairs being exploited and unreasonable hosts. So just want to check that I'm not expecting too much.
My summer Au Pair (around 6 weeks) will be in sole charge of 3 DDs (aged 10, 8 & 4) for around 3 hours, 3 days a week whilst I work as well as a bit of evening babysitting. No cleaning etc. as have cleaner. I'm thinking of Au Pairs in their early 20's with some babysitting / childcare exp.
BUT....
is it reasonable to expect an Au Pair to look after 3 children for 3 hours alone? Has anyone any experience of this?
Look forward to your thoughts!!

Yes, sounds fine. Most au pairs do 25ish hours a week of childcare for school age children - eg. 7am-9am and 3pm-6pm.

Sounds fine....

I think it depends on your children (how well-behaved they are and how easy they are to supervise/entertain) and of course the au pair's experience and what you would expect her to do with them. If you have any doubts about whether they might be difficult to manage, I would start off with low risk activities or outings.
