This product is wonderful! It's kept my little one from chewing on my legs and any other body parts that he's been able to find! My only critique is that he is 10 months old, and a skinny little guy, and the wrist band is too big for him. I also turned the wristband around backwards, so the scratchy part of the velcro is facing away from his skin instead of towards it. I'd love to see a second wrist piece sent for extremely tiny kiddos.
