Experience as an au pair!

Hello everybody, I would like to share my experience as an au pair (and of course practise some English!)
So, I'm soon going back to France nearly, on 17 of August, I'm there I've been here since 24 of May.
It was a good experience, I arrived with a very low level in English, now it's better! I think it's the best way to learn English (or another language!).
I have two families, one who hosts me, feeds me, and the other one pays me! There They are neightbours. I'm working for both families! I have two girls in one family and two as well in the other one. 

They are 4,7,6,3 years old! I'm doing some housework but most often I'm looking after children. I play with them, drop them to their activity (swimming, gym, ballet, tennis).
Now, my trip is nearly finished, but it's a very good experience when you have a good family who helps you and integrates you into their family.
But for me, 3 months it's is enough, because I miss my friends, my family, I need to go home now.
I would like to speak English fluently, so I am not enough brave enough for to stay for one year. So, now I'm looking for an exchange partner, I think that the next year, I am coming going to England again but I don't know where for the moment.
Thanks for reading me!

Hope that helps!
