|SIZING CHART||Age: 3 to 4||Age: 5 to 6||Age: 7+|
|Recommended Appliance Size||Small||Medium||Large|
Please note that for children younger than 3, the small size can still be used. HOWEVER, the success rate cannot be claimed to be 95%, because very young children are more likely to switch from thumb to finger sucking, or vice-versa, due to their habit not being fully matured.
If your child is between sizes, please see our “sizing guidelines FAQ”.
