Just that really. We are moving abroad, and 5 year old DS will be going to an American International school (class will be about 60% American, with an American teacher and a mix of other nationalities, but he will almost certainly be the only British child - they have I think 5 British students in the schools which has a role of about 400).
I don't want the poor little thing to be even more confused than he will probably already be, having moved continents the week before, when he starts school, so am trying to introduce a few American words to help him to find his feet. I have sneakers, faucet, sidewalk, eraser (!!), pants (also likely to be a source of hilarity), restroom.... what am I missing?
