Well, in several other threads I posted my thoughts on harnesses. Now I have to take back some of what I said. I mentioned that, while I understood the utility of these things, I would never use them.
To that end, in order to avoid using them myself, dh and I would take our 3 kids to the mall every weekend and take (specifically) the twins out of the stroller and have them walk holding our hands. We started doing this at the start of the year figuring that in 3 months, they'd get the hang of it.
Well, we leave for the world in 2 days -- the weather this past weekend was GORGEOUS so we took the kids to the National Zoo (only about 25 minutes from our home) -- this would be our final test. DD(2) FAILED MISERABLY!!!!! In fact, she did so poorly during this zoo trip that when we got home and naptime began, dh had to run out to Target and buy 2 harness backpacks (can't buy one for her and not her twin).
In order to see how they worked, I put the harnesses on the twins and took them for a walk in our neighborhood that afternoon (still quite warm and really need to take advantage of the nice weather when we get it). And it cemented my attitude that these are just leashes but cuter. I felt like I was out walking the dogs. However, I'd rather take the twin dogs for a walk through the world then spend my trip frantically looking for one of them when they (well, likely SHE) disappears into the crowd.
So, I'm sorry for my previous "holier than thou" attitude -- I too must use these harnesses/leashes.
But it's more important that my kids are safe, regardless of my personal feelings about these things, right?
