She figures it all out!
I tried the Braceability and it protected her from thumb sucking teeth, but came at the expense of her happiness because her arm was totally immobilized like in a cast. Since she’s six, it took no time for her to take it off. Finally, I dipped my pocket and purchased two Nipit hand stoppers. And just like that, mom was in command. Now, she’s two months free of thumb sucking, thanks to the Nipit.
