dd (nearly 5, year 1) - ballet on Tuesdays.
ds (6.5, year 2) - tae kwon do on Tuesdays, swimming on Saturday mornings.
Both are on a waiting list to do a drama club at weekend.
Any more than that & we'd be underwater I think - their school day is long (up at 6.45, home around 4) and although the homework is not that exacting I feel doing it in an unpressured way should be our priority, at least for the start of the school year.
Also thinking that Blue Peter at 5 on Wednesday should be considered a formal "activity".
