How do I get my child to stop sucking his thumb?

Babies are born with a need to suck, which provides both nutrition and comfort. Most children stop sucking their thumbs or pacifiers before age 3 or 4, but up to a third of preschoolers and even a few older children continue to suck their thumbs for at least part of the day. For these children, thumb sucking may help to relieve stress and can be soothing and relaxing, especially when falling asleep.

Frequent thumb sucking beyond age 4, however, may be a sign of insecurity or other emotional problems. It also can lead to dental problems. Moreover, some children can be teased about thumb sucking, both by peers and adults, which usually leads to self-esteem problems.

There are specific things you can do to help your child stop sucking his thumb, but keep in mind that this will only be successful if your child wants to stop. Try to be sympathetic and supportive, and don't criticize or punish him. Gentle reminders may be enough to reduce the frequency of the habit. Ask your child how he would like to be reminded if he forgets, for example, with a gesture or 'secret' word. Praise his efforts. Try giving him small rewards (for example, a sticker chart) for remembering not to suck his thumb. Gloves or socks on his hands at night will remind only him and not expose him to teasing by others.

If your child continues to suck his thumb, despite these interventions, or if the thumb sucking is interfering with his friendships or activities, discuss it with his pediatrician. If you have any concerns about his teeth, make an appointment to see his dentist.
