Many babies and toddlers suck their thumbs. Developmentally, it’s completely normal. But most little ones also eventually stop sucking their thumbs between the ages of two to four years old. It’s when they don’t kick this habit by that time that it can become problematic, leading to dental issues such as bite problems or misaligned teeth. But luckily, with the right strategies, you can help your child stop sucking their thumb fairly easily, without all the tears and stress.
Why Kids Suck Their Thumbs (& Why it Matters)
Thumb sucking is a common self-soothing behavior, and many toddlers engage in it when they’re tired, anxious, or beginning to fall asleep, but as the American Dental Association notes, this normally stops by around age four. But some kids may continue to suck their thumbs as a method of comforting themselves past the preschool years.
That’s usually problematic, because prolonged thumb-sucking leads to many oral issues, such as:
- Thumb sucking teeth damage
- Changes in the jaw or roof of the mouth
- Speech issues and social challenges
- A higher likelihood of needing braces
Should You Try to Stop Your Kid’s Thumb Sucking Habit?
Yes. If they are over the age of four or you start noticing changes in their teeth, then it’s a good idea to start the process of breaking the habit gently.
5 Thumb Sucking Remedies That Actually Work
Here are five proven strategies for helping your little one stop their thumb sucking habit.
1. Create a New Bedtime Routine
If your little one tends to suck their thumb around bedtime, try replacing thumb sucking with other creature comforts, like a soft blanket, calming music, or engaging bedtime stories. Gently remove their thumb from their mouth while they’re sleeping if necessary.
2. Keep Them Busy
Similar to the way that telling bedtime stories keeps them occupied, keeping your little one’s minds – and hands – busy can help them stop them from sucking their thumb. So occupy them with puzzles, crafts, or anything else to keep them busy. This can be especially helpful to implement when they’re watching television, which often leads to unconscious thumb-sucking.
3. Use a Thumb Sucking Habit Breaker
For kids whose habit is a bit more pervasive, you might consider trying gentle habit breakers like wool or fabric mittens, thumb guards, or non-toxic bitter nail polish. These help your child develop awareness of when they’re sucking their thumb without feeling punished.
4. Praise Their Progress
Be sure to celebrate their wins with rewards like stickers, extra storytime, or high-fives and compliments. Varying rewards can be helpful, as can alternating between praising and withholding praise (within reason) so that the act of giving them praise remains meaningful. But remember, overall, praise works better than criticism.
5. Identity & Address Specific Triggers
From stress to fatigue to boredom, there are many things that might cause your kindergartener or grade school-aged kid to suck their thumb. Keep track of what they are, and then use the above strategies to pinpoint each of them. You may find it helpful to provide them a calm-down space, break time, or even a micro cuddle session.
Final Thoughts
If you’ve tried these tips and your little one continues to suck their thumb, then it may be time to talk to a pediatric dentist. There’s a correlation between thumb sucking and braces. That is, if you can’t get your child to stop, they may require braces (which can be pricey) down the line, when getting them might otherwise be preventable. So reach out today for help if you need it!
