how can i get a kid to stop sucking their thumb?

@AnukBinary shes 12

@Miajackson oh okay, thanks for telling me. Its probably a security habit that makes her feel calm and safe in a comfort zone. Rather it be consciously or subconsciously.
Maybe try and replace it with something else that will peak her interest and keeps her hands busy.

One thing you should not do, is criticize, talk down, or mock her thumb sucking. It could make things worse and turn it into a nervous tick.

@AnukBinary i never mock her i just tell her its not good to suck her thumb

@Miajackson That's good. I had a cousin who sucked his thumb at that age. I remember my aunt kept his hands busy to help out
