Been looking at some of the responses to the article. Quite a few responses wonder why parents can't provide a bowl of cereal and milk, or some toast, or porridge. None of these are expensive. I went right through school having a bowl of cornflakes and milk for breakfast every day. My parents weren't poor, but their parents had been and yet they had always been given breakfast at home too. At least, my dad was until he got into his teens and couldn't be bothered to get up early enough to both eat breakfast and get to school on time. I bet there's still a lot of that going on.
By the way, from when I was eleven and starting secondary school, I got my own breakfast and left the house before my mother even got up. Well, she was drinking coffee (made by dad) and preparing herself to face breakfast with my three younger siblings.
I have a few doubts about the numbers quoted in the article. I fully agree that children need breakfast.
