You can apply fluids on the thumb of the child. Once you've talked to the child and explained that thumb sucking is not a good habit, tell them to make a goal to learn how to stop. The bitter liquid on the thumb of the child will act as a rest for the goal they must reach.
Wait for the children to find some kind of motivation and use it to stop the habit. For example, once they start preschool and become more involved with other young children, you can show them that they are too old to be sucking their thumb and give them examples of other children who are of their age at their preschool and do not suck their thumbs.
Engage children in more activities that require them to use their hands. This will help distract the child from the habit.
Be patient with the child. You should not try to forcefully stop thumb-sucking habits of a child before they even seem to be willing to quit on their own.
