My son is a runner and after almost being hit by a car we decided it was time to do something about it. I have always been one of those people that definitely judged people that had their children on leashes. That was until I had Vincent, the most rambunctious, defiant child to ever exist. After reading reviews and looking at countless options (because those simple wrist leashes were not going to work for my situation) I decided to give this product a try. I love that it looks like a book bag and that it gives him something to carry his many trinkets in. The harness part is fantastic and near impossible for a child to remove (and mine is a regular Houdini). So parents with little ones you just cannot tame, stop pulling your hair out and buy this product! Will other parents and strangers out and about judge you, why yes they will! But will your kid be free to live another day? Yes they certainly will and that's all that matters!
