What Is the Cause of Thumbsucking?

Thumbsucking

Thumbsucking is a common habit in babies and young children. It is estimated that up to 40% of babies suck their thumbs, and about 20% of toddlers do. Thumbsucking is usually harmless and outgrows itself by the time a child is 4 or 5 years old. However, in some cases, thumbsucking can persist into childhood or adulthood.

There are a number of possible causes of thumbsucking. Some of the most common include:

Instinctual need

Babies are born with a sucking reflex, which helps them to get food and comfort. Thumbsucking can be a way for babies to satisfy this need.

Boredom or anxiety

Thumbsucking can also be a way for children to self-soothe when they are bored, anxious, or stressed.

Sensory stimulation

The act of sucking can provide sensory stimulation that can be calming or pleasurable for some children.

Learned behavior

If a child sees another child sucking their thumb, they may be more likely to start doing it themselves.

In most cases, thumbsucking is not a cause for concern. However, if thumbsucking is causing problems, such as dental problems or speech problems, it may be helpful to try to discourage the habit. There are a number of ways to discourage thumbsucking, such as:

Positive reinforcement

When your child does not suck their thumb, give them positive reinforcement, such as praise or a small reward.

Time-outs

If your child continues to suck their thumb, you can give them a short time-out.

Thumb guards

Thumb guards are a device that can be worn over the thumb to make it difficult to suck.

Behavior modification therapy

Behavior modification therapy can help children to learn new ways to cope with boredom, anxiety, or stress.
If you are concerned about your child’s thumbsucking, talk to your pediatrician. They can help you to determine if thumbsucking is a problem and offer advice on how to discourage the habit.

Here are some additional tips for discouraging thumbsucking:

  • Make sure your child’s nails are trimmed short to prevent them from scratching their gums.
  • Keep your child’s hands busy with activities, such as playing with toys or drawing.
  • Have them put on gloves to stop them from sucking their thumbs.
  • Offer your child a pacifier or other object to suck on instead of their thumb.
  • Set a good example by not sucking your thumb yourself.
  • With patience and consistency, you can help your child to outgrow the habit of thumbsucking.
