Very true, peer pressure can effect the choices our kids make. Our little boy choses to take a packed lunch every day. I make him sandwiches (usually ham or beef), and he also takes a yoghurt/fromage frais, a biscuit and a little box of raisens
At the moment I don't think he'd choose chips if he had school dinners because he really isn't a big fan of chips or fries. He doesn't even eat them if we go to McDonalds.
