No, you're right. I think the scary thing about the programme was the way people were playing on their child's strengths to the exclusion of everything else.
So yes, if you have a maths whizz, introduce him to multiplication and let him play around with it. If you have a freakishly early reader, provide him with the complete works of Roald Dahl and be around to share his enjoyment of the story and the word-play. Take him to museums and let him read books about Egyptian embalming if that's what floats his boat.
But also encourage him to do things that maybe don't come naturally to him, and things that he has to struggle with, so that he learns important skills like perseverance, and understands that you don't always have to be the best at everything and that things can be worth doing even if you can't do them perfectly.
So if I had a sport whizz I'd be encouraging him to read Horrible Histories and play number games as well as doing football and swimming practice. If I had a music genius like the girl in the programme I'd be encouraging her to join Brownies and go to art club as well as doing piano concerts. And if I had a genius mathematician I'd encourage him to maybe join Stagecoach or swimming club as well as enjoying his numbers.
Balance is the thing, IME.
