Review on 🦾 Top-Quality Pediatric Toddler/Kids Elbow Immobilizer Stabilizer Splint / Arm Restraint by Matt Williams

Definitely works to keep my son from putting his thumb in his mouth. It doesn't look particularly comfortable, so I only leave it on for about five to 10 minutes throughout the day, which is enough time to take his mind off things other than thumb sucking. It should also not be too tight so that the elbow does not bend. In fact, my son could bend his elbow and put his thumb in his mouth, but holding it in that position is uncomfortable for him to let go of. Again, in my opinion, this isn't something you can wear all day, just a few times a day is enough.
