The parents involved mustn't be as smart as their kids or they'd never have agreed to this. Children have enough to put up with without the added pressure of being fodder for the goggle box.
The family that force feed their child some vegetable shake thingy to enhance brain power need to drink it every day for years. I had to stop watching it.
If the child insists on competing in this, its fine by me.
BUT there should be no influence by the parents, thats where trouble starts.
Nothing worse than pushy parents.
