We eat very healthily (though I eat far too much!) and my son, like yours chooses healthy options naturally. He actually won't eat chips or drink fizzy drinks as he doesn't like them (though I suspect that will change as he approaches teenage). He's at the age where he likes to run about all day, and he's not allowed on the computer or Wii for more than an hour at a time. So far, so good. But I do expect that if he changes those habits later, he will turn to fat the way I did and the way his dad is going... I'm not convinced we did. I think we ate a lot more homecooked meals (as opposed to orange freezer junk) and portions were definitely a LOT smaller. Your observation about your fish supper being a case in point. As regards expercise, Beth is definitely right. When I was a kid, living in the next village to where I now live, it was normal for us to go out all day playing, climbing trees, exploring the rocks (over the cliffs!) at the beach and building dens and dams. I was chastised recently for allowing my child (aged 8) and his friend to play in the woods directly behind our house in case "something happened to them". Now what do you suppose would happen to them? Statistics show there is no greater risk to children today than 30 years ago and yet parents keep their children indoors for fear of some threat to their safety. Where we live, much of the beach I used to play on is now privately owned, and the fields where we used to play now has houses on it.
