He is a bright boy!
Do not feel bad about wanting the best for your child. If he gets too bored he will get disruptive, and that doesn't help anyone. They don't have them in Queensland, but in New South Wales they have special schools for gifted kids which are public and there are no fees. Shame they can't have that in the UK too.
e rings a vague bell - but my supersmart DH has gone to work so I can't ask him, he would say oh yes it's blah blah blah - don't you remember I love that he is so smart, it's very appealing. So your boy will probably find a woman who thinks smart is sexy too!
