What is funny about this harness thing, is that I haven't used one but I wouldn't be opossed to it if someone has. I actually don't own one. What I don't approve of and have a hard time with is that "I'm right and everyone else is wrong and lazy" opinion. What about crazy busy with two very young walkers who scream to get down because they are tired of sitting in a stroller and also my poor back to bend to their level to walk for any distance I'd be walking like I'm 90 years old bent over that far. I don't think either style is right or wrong, I think it is what you have to live with. I'd much rather see a parent with a harness and have their child alive and well, then dead or missing. There is also the opinion of letting a child explore a little and still have them within a close distance, that is boundries but also independence (which is something my parents taught also, and I have handled responsiblity well from a young age). I don't want to always have to be yelling no, children are curious little people, and want to explore, this gives them a safe way to do that also. I hold hands, as I said I don't even own a harness but it is something I would consider and most of all in a place like WDW. We go to Hersheypark as we have season passes and I haven't used one there but again if the need is there I'm not against it. Just remember you're not ALWAYS right and I'm sure just as no one here is the perfect parent or a parent that has perfect parenting skills.
