We get involved with the Little Athletics program that is run on the school grounds, this is open to anyone, not just children attending the school, and Charlie plays soccer with the local team. Think they play alot of school sport in the higher years but mine aren't there yet so don't really know.
As for your second question - our eldest had a horrible time with bullies in the UK, so this was our biggest worry. Have to say, both my children were welcomed from day one and Ellie-may is like a different child. Her confidence is soaring so can't tell you how relieved we are. I am sure some difficuties, and mine are quite young still so I think fitting in is a bit easier, as friend groups are still pretty fluid - but I can only comment on our experience.
We have no regrets so far about them being in the school - happy children make happy parents!
As a side note, they also have a really great OSHC service - mine love to go, particulaury in the holidays when they get to on on great days out.
Hope all goes well for you.
