Our toddler is a runner and loves to explore which makes outings very stressful (especially when it's with only one parent!) We wanted to allow our child to explore her world, but give us peace of mind that she has not somehow ran at the speed of light away from us when we are shopping. This backpack has given us exactly that!We love that the tether is detachable, so we can remove it at anytime if we want, but it won't come off on its own due to the clasp. The backpack also has a ton of space, so I make my toddler carry her own snack and/or any toys she wanted haha! When she doesn't want to run around, I will throw my keys and wallet into it as well, as it's easy to put over one of my shoulders to replace my purse.The backpack is also soooo cute! I wanted one that wasn't super childish and that felt more fashionable. The backpack material is quality, shimmery, and it's perfect.This backpack has given us so much quality of life back because we are all happier knowing our child is safe, but also being allowed to learn and explore. Don't let any naysayers stop you from getting a safety backpack! It has allowed our family to be the parents we want to be to our child (happy and not stressed!)
