Wow he does sound like bright cookie! Neither of my two have shown any early aptitude for anything like that, although my son has always been ahead of the game with his physical ability. Keep persevering with the swimming, both my two have gone through fazes of hating their lessons but both love them now. It would have been so easy to give up, but we kept going every week. I think it is a most important skill to have.
Oh dear, I am home now with a very miserable little girl who is dozing in the bed next to me. Her resp rate is quite high, and her temp soaring so I think we will spend our arvo in the drs. Just waiting to pick up my big boy from school first - he'll be gutted that we can 't go straight home and play with his friend from up the road.
I did manage to pick up my kettlebell on the way home so I've got a new toy to play with this evening.
