Hi, Have you tried play doh? Its messy when it gets in the carpet, but, my daughter is also a thumb sucker, and when her hands are busy with play-doh, she doesnt suck her thumb as much. My dentist also suggested putting socks on her hands, to remind her not to do it. His son also sucked his thumb, when he was little, but now that he is a college grad, he is too busy!! LOL D.
