As children grow and develop, their need to suck typically goes away, most often by the time they are 6 to 8 years old. Also, with increases in peer pressure, children are more able to control their behavior. However, parents sometimes want this behavior to stop before peer pressure becomes an issue.
If you want to break your child’s pacifier or thumbsucking habits, the first step is to ignore them! Most often, they will disappear with time. Harsh words, teasing, or punishment may upset your child, and the habit will get worse. Punishment is not an effective way to get rid of habits.
