Finger Sucking

Put the THUM no suck stuff on Sophies finger to help her stop sucking her finger...I am writing the company, it is made from Cayenne. Well, guess what , she LOVED it. Made it taste like a big candy stick so she had it more in her mouth and was begging for more!!! You know if they can put a tub of berbere and chili's jalapenos, and habeneros on stuff and eat it like candy...what do you do???
