Somebody I know (not exactly a friend) has recently started childminding. She was commenting on the appetite of one of her charges(whose mum I also know) She was telling me that in one afternoon this 2 yearold had cheese on toast for lunch, followed by three packets of crisps, a mars bar, chocolate buttons and a few other things I can't remember. I would be horrified if my kids were being fed like this, and I'm pretty sure this boy's mum would be too.
Should I say something, or is it really not my business?
