I don't think there's anything wrong with parents giving their kids chocolate, sweets or this kind of cereal, it just depends on how much or how often.
I loved running to the shops with my pocket money and stuffing my face full of junk food. They're only kids once, I say let them enjoy themselves.
But fatties with fat kids with fatty food in their fat trolley, yeah I hate that.
And lion bar cereal is freaking awesome! Try it!
