DH and I have pretty much decided that we want an au pair to help us with school / nursery pick ups and after school care for our two children (will be 4 and 6). The au pair would walk them home from school and look after them on her own for about 3 hours every day, plus occasional babysitting.
There are two au pairs that we like a lot and are trying to decide between. Both would come from the same European country and are keen to stay for a year. One is 17 (would turn 18 shortly after arriving) and the other is 22. We have a slight preference for the 17 year old, as she likes doing hobbies that we enjoy and her English is better.
Would we be mad to go with the 17 year old au pair?
