We love this sleepsack walker, it's so comfy, our toddler is so cuddly in it, BUT the only thing that bugs us is the zipper doesn't go all the way to the top, so while there is a clasp there, it doesn't actually cover the zipper. Meaning, our toddler can easily unzip the sleepsack. I'm going to sew another strap and snap on a little lower to fully cover the top of the zipper.
