What do you think about using a child harness on a toddler?
I agree with you Sarah. I actually have not used one because James freaks out everytime I try to put the little backpack on him, but I think they are totally fine. In a crowded place your child's safety is super important, and you have to keep them safe one way or another. A stroller might looks less mean, but it's much more restricting and not as fun for the kid. I have heard stories of people's kiddos being saved by a backpack harness when they were in a crowded place and someone tried to snatch their kid. Especially with two small kiddos to chase after, I think they're great, and I really wish people would be less judgmental about them... Of course I am referring to a cute little backpack with a tail or something, and not swine around the wrist or anything like that.
I agree with Sarah and Grace, and actually just purchased a cute lion backpack one for Teddy. There are situations where being in the stroller can get very tiring and constraining for Teddy but allowing him to run free also isn't an option - like the airport, a busy crowded fair or shop, etc. I imagine especially when you have more then one child that they can be a big help but no matter what I think they are fine. I mean holding a parent's hand is more constraining (and tiring!) then having a backpack on.
