Lee bee, I agree, kids need to be active as young as possible so it becomes their lifestyle! Obesity and lack of exercise in kids is rising. Yes, the strollers/wagons come in handy and are sometimes needed but I don't think they should be used all or even most of the time.
Suzie, we sound alikeI think I've told this story before but one day when crossing the street, 2 of my kids would have been run over by a car with a distracted driver. Had they not been wearing harnesses and I pulled them back, things would have been very different! It's not just the kids that we need to trust/watch over, it's the idiotic drivers too!!
