Both my kids did/do it too! I haven’t figured it out with my 8mo old,but my 15yr old did it until she was 6! 😳
This worked for my son he sucked his thumb and first two digits so the thumb and finger covered helped. There are some with only the thumb covered I don’t think it would’ve worked. If you think you’re son will take it off. I would try an arm brace we used that as well. It didn’t hurt my little one and I was ok with it. Stopped thumb in finger sucking in a couple weeks. For good!
