(AGE0-1) Finger Sucking Stop Thumb sucking,Kids Finger Stop Infant Finger Sucking

I have a nighttime thumbsucker, who got a nasty infection on his thumb. This item is a good concept but the strand that tightens around the wrist needs improvement. The plastic piece that the strap threads through is open on one side so it is very easy for tiny fingers to do a little one two magic, and poof! It's somehow made its way off the hand. I think a snap closure or very strong velcro would work better. My son usually has this worked off his hand within minutes of me meticulously putting it on him...lol
