If you notice your child sucking their thumb when they want to feel secure, start engaging them. Make sure to give them a hug and hold their hands. If your child is a little older, ask them questions about why they feel insecure or scared. Don’t let them suck their thumb at this time. The child will slowly begin to depend on you for comfort and security instead of sucking on their thumb.

5. Praise Or Reward

Praise or reward your toddler every time they do not have the thumb in the mouth. Give a sticker for every hour your child goes without sucking their thumb. This may provide encouragement and make them put more effort into quitting the habit.

6. Avoid Using Finger Gloves/Covers

Don’t put on a pair of gloves/covers on your toddler’s hands to make him/her quit the habit. This will only increase your child’s anxiety. And when they are old enough, they may just remove the gloves and suck their thumbs again. Instead, help them out of it slowly.

7. Divert Their Attention

Try to divert your baby’s attention every time you see him/her sucking the thumb. Give them a stress ball if you think they are sucking their thumb when they are nervous. If the toddler has been thumb sucking when bored, make them draw, paint, or play with toys as a distraction.

8. Be Patient

Remember, thumb sucking is a common habit in most kids. A majority of children give up sucking their thumb on their own with time. So, be a little patient and wait for them to stop it on their own.

While thumb sucking may seem soothing and calming to the baby in the initial stages, it also comes with its share of side effects. These side effects are usually quite gradual and occur in those children who suck their thumb vigorously and all too often.

Thumb sucking in babies and children is quite common and is considered a manifestation of their natural rooting and sucking reflexes. Babies may begin sucking their thumbs for self-soothing and a sense of comfort soon after they are born. While most babies drop this habit by the time they reach six months, the child needs an intervention if the habit continues. The habit is not only unsightly and unhygienic but may also lead to oral structural deformities once the permanent teeth start showing up. Therefore, constant counseling or therapy is necessary once the child is old enough. Diversion techniques, patience, ‘chewellry’, praise and reward are some of the common practices to help children let go of a thumb sucking habit.

Frequently Asked Questions

Which is worse – the thumb or the pacifier?

Interestingly, both the thumb and the pacifier move a baby’s teeth similarly. Sucking on a thumb or a pacifier is not always harmful unless it develops into a habit. Even using finger guards can turn into a bad habit. You must ensure that the baby stops before they reach the age of three. Beyond that age, it can impact their dental development, resulting in crooked permanent teeth, a misaligned bite, and speech issues. However, remember that the pacifier can be removed, whereas the thumb cannot! As a result, pacifiers are preferable to thumb sucking.

Is thumb sucking hereditary?

No, thumb sucking is not hereditary. It is usually an indicator of a baby’s feelings of insecurity. Such babies need constant support from their parents who must try to wean the habit through gentle methods and perseverance.

Can thumb sucking recur or return after it has been successfully stopped, and what are some preventive measures?

No, thumb-sucking cannot recur or return after it has been successfully stopped. It usually ceases to happen after 2-4 years of age. A few preventive measures could be using chewers, guiding them about germs, or diverting their attention.

Can thumb sucking be replaced with another behavior or habit, such as a comfort object or fidget toy?

Yes, thumb sucking can be replaced with another behavior or habit, such as a comfort object or fidget toy as it would divert their attention and keep them engaged. Some calming activities such as playing with puzzles, or popping bubble wrap might also help.

Key Takeaways

  • Thumb sucking can spread germs and damage your child’s teeth alignment.
