When I was in Senior School, I had an 8 mile bus ride before getting home and many of the children on the bus would be eating something, bearing in mind that we had been at the bus stop from 8.15am and arrived home at 4.30pm. School dinners were, well, school dinners - I'll say no more (but parsley sauce on cooked ham, ugh still can't stand the smell of parsley sauce). My brothers went to school in the local town so always left after me and arrived home before me. We were all very sporty, didn't eat many sweets or crisps (couldn't afford it) and ate healthy meals made from scratch, even though my mother worked until 5.30pm. As I got older I cooked so a meal was ready for mam when she got home. My brothers had very healthy appetites and I remember an aunt saying to my mother one day that they had 'hollow legs' as they ate so much. I tried to carry this through to my own children and it was a very rare occasion when they had sweets or crisps on the way home from school. They were mostly quite sporty and all of them were thin as rakes when they were growing up - a height spurt, put on a bit of weight, then another height spurt and so on. They all appear to have carried this on with their children and don't provide sweet or crispy snacks after school.
