Thumb sucking and pacifier use is one of the most common concerns we hear at the office. Thumb sucking and using a pacifier is totally normal up to a certain age, and usually goes away by itself as your child begins to eat solid foods. Let’s discuss why children suck their thumbs and use pacifiers, and when it becomes a cause for concern.
When babies are breast or bottle feeding, their tongue moves forward between the space in their upper and lower jaw as they swallow so that a seal is created with their mouth, and milk comes out of the nipple. Thumb sucking and using a pacifier can be soothing to babies because it mimics that movement and (hopefully) allows your child to self soothe. Some babies even suck their thumbs or fingers in the womb!
What happens when thumb sucking and pacifier use goes on too long?
If thumb sucking and pacifier use goes on too long, teeth and jaw development can be impacted. Kids can develop an ‘open bit’ which means that there will be a space between the upper teeth and lower teeth when the jaw is closed. The upper teeth can also be pushed outward when fingers and thumbs are in the mouth past age 3 or 4. The roof of the mouth can also be impacted.
When to stop:
As with most child related topics, there are a WHOLE lot of opinions on when you should stop using a pacifier and thumb/finger sucking. Generally, kids will stop on their own as they eat more and more solid foods. Sucking will no longer provide comfort when they’re breastfeeding or bottle feeding less. If your kiddo does not stop on their own, we recommend that you start the process at around age two if your child has not stopped on their own. We want to be sure to emphasize the word START in the previous sentence. This is something (unlike potty training; don’t even get us started) that you can take your time with.
How to stop:
Keep in mind that if you start around age 2, you have plenty of time to stop by the age 3-4 ‘hard stop’ recommended by the American Academy of Pediatric Dentistry. Start slowly by trying to eliminate pacifier use or thumb sucking for certain times during the day. Slowly increase the amount of time your kiddo is going without. Use gentle reminders if you notice them sucking their thumbs or fingers during the times you’ve designated. Be sure to give lots of praise when you notice your kids aren’t using a pacifier or sucking their fingers/thumb. When it comes time to eliminate the behavior at nap or bedtime, involve your child in choosing a new comfort. Pick out a special stuffed animal, or have a new blanket made for them that is only used at sleep time. If they’re old enough, you can also use a reward/star chart! We’ve also heard of parents using a ‘binkie fairy’ to make the final leap into no more pacifier use. Kids put their pacifiers in a bag, and tie the bag to a tree outside before they go to bed. When they wake up, they’ll find that the binkie fairy left a toy for them in exchange for the pacifiers.
