Sorry for barging in here - being Swedish living in Sweden.
I have recently returned from two years of expating in Thailand. In Bangkok my 7-year old son went to an international school and became really good at speaking english. Most of his teachers were american and hence also his accent. Now I'm looking for a young teacher or maybe an exchange student for some tutoring in a playful way a couple of hours of week. Preferably by someone that speaks english like a native.
It would also be great to get to know some expat families and arrange playdates where he can practice his english.
