DS is very sporty, and esp good at swimming. He's just been 'promoted' into a special kids section of the, quite serious, club at our local pool. There are 4 8yos, ds, and 1 6yo (son of national champion or s'th). They swim from 7.15 to 8.45pm twice a week, basically doing lengths of a 50m pool.
Now, quite apart from the fact that he goes to bed at 7.15 on the other evenings, is this a bit much anyway for a 7yo? I don't want to stand in the way if he's going to be an olympic swimmer or something, and I realise it's a sport that starts very young, but I'm concerned he'll be exhausted.
