Hi.
There is a ballet class for children age 3 and up that coincides with the school terms. 2 expat mums teach the class. The fee is K15 per class and is payable on the day. As attendance is so sporadic the classes arent very formal - but the kids love it and it gives them a good introduction into ballet (and also offers something else to do on a saturday morning!!)
You can find out more through the schools - or message me privately and I'll give you some details.
