DS asked for some crisps for a snack, I said yes he could have some. DH started going on and on about how he should have grapes instead, or kiddilicious baby crisps.
I do all meals and snacks for both, as DH working in study.
I really try my best to cook with the children, encourage plenty of fruit and veg in their diet, and every so often if my son asks for crisps, say yes. I can't get worked up about it, but DH says they will make DS 'uncultured'
