To me, it's so sad to watch generations of kids grow up fat and sedentary, already showing signs of heart disease, diabetes and clogged arteries, that I'd cheerlead any effort. And one thing I especially like about the Teletubbies effort is how playful and unstructured the exercise stuff is. That's what playtime is all about. Whether any of this will make a dent in the horrible problem of childhood obesity remains to be seen, but hey, you gotta start somewhere. The truth is, schools are doing a rotten job promoting kid fitness.
Parents appear panicked and helpless.
You can't depend on a TV show or book or video to inspire your kids to be more active and more aware of the food they eat. That's your job. Be a role model. Let kids see you make time for play, for fun. Don't diet or obsess about food.
