Rating : - Worked like a charm I wish I knew this product before, it really worked. My 6 1/2 year old daughter used to suck her two right hand fingers all night and also in the day time. I was skeptical about trying this product but tried it after reading lots of good reviews on amazon. I applied nail paint on her fingers and put a coat of mavala stop on top it. Before applying it on her fingers I tasted it and it was really yuck. On first night she tried to suck her fingers and she found out that it was too bitter and yucky, she even tried to wash it off. The product worked from day one and she never sucked her fingers again. Its been more then 2 weeks and looks like she gave up on sucking her fingers.
