Sizing Chart

SIZE CHART: Age / Weight Age: 0 to 4 (under 40 lbs) Age: 5 to 6 (between 40 and 55 lbs) Age: 7+ (more than 55 lbs)
Recommended Appliance Size Small Medium Large

The chart shown above will work for the majority of children. If your child is in between sizes (for example, an almost 5 year old who weighs 40 pounds), choose a smaller size if you expect the child to resist the treatment. Also, consider the child’s height: if the child is very tall for their age, use a smaller size, since their fingers tend to be longer and thinner. The only important parameter in sizing is the diameter of the finger in regards to the tubes.

Please know that children under 3 are more likely to switch from thumb to finger sucking, or vice-versa, due to their habit not being fully matured. If you see that the child switches from thumb to finger sucking, please contact us.

    My 4.5 year old has sucked her fingers all her life, night and day. During Covid, that became a serious health issue. I’ve been trying to break her habit for well over a year. After trying every other suggested trick, I bought these, very pricy when you live in Canada. We are 6 weeks into our journey and here are my thoughts:
    1) product works but kids are smart and can escape them (I had to tape them onto her hands so she couldn’t skip her fingers out).
    2) the thin wrist bands for securing the guards cut into my kids’ wrists and required padding under to avoid sores. Also rubs between fingers and creates sores so bandaids were needed there
    3) kids are resilient. Mine has had no trouble living life normally with these guards on both hands 24/7.
    This has been the only product/method with ANY success for us. Now my daughter takes them off during the day (while supervised) and then wears them at night. It’s been a life saver, but not easy. Will be worth it in the end.

    It helped my 4 year old daughter break the habit!I am really happy! Although it’s not a cheap product I totally recommend it!

  3. Ann Johnson

    This was just what my son needed to kick the habit! He was wanting to and was ready to quit, but it was so tough for him to stop. He would end up with his fingers in mouth during sleep, and he had trouble not falling back into the habit when mindlessly watching tv or riding in the car, etc. After one week, he felt he’d stopped, but we kept it on another month before declaring him free of the habit. Wonderful product, thank you!

  4. Miriam Vasko

    This product was a lifesaver for us! It helped my son break his finger sucking habit at the age of 3 years. He has sucked his index and middle finger since the age of 2 months. In 30 days the habit was broken and we are so thankful for this device!

  5. Erica

    We weren’t sure how to break our 8.5 year old of her finger sucking habit but it was so clear the habit had changed the shape of her mouth and teeth we needed to do something. A friend told us about the finger guard about 6 weeks ago and we ordered it immediately. Our daughter promptly named it the “Invisihand”! It was very rough for the first 3 nights. She couldn’t fall asleep and had to sleep in our living room instead of her bed. But after the first 3 nights she was able to fall asleep in her bed (stays up later to read to get sleepy) and we haven’t had an issue since. We decided to continue using it because she has had the habit for so many years and we want to ensure she won’t go back to sucking her fingers. We even forgot to put it on one night and she did not put her fingers in her mouth! We are so happy with this product from the comfortable design, ease of ordering, quick shipping and mostly the success we’ve had. Thank you!

    We are very thankful for this product that was recommended by our pediatrician. It worked for our toddler! It was tough at first but it really did break the habit.

  7. Jose Prado

    my 2 year old son used the tguard for 4 weeks and it was enough to stop sucking his fingers!!! Recommended 100%

  8. Sandra Rodriguez

    My 3 year old stopped! I’m so happy. I told her she had to stop in order to go to school (preschool). She was so happy about but didn’t do anything. When we got the TGuard she was very excited, loved the color belts and the stickers. She only wore it for less than a week and promised not to suck any more. I was skeptical but she really did. She used to suck her 2 (middle and ring) fingers all the time, and she really stopped. I’m so proud. She didn’t need much use of it but getting it make her realize that she needed to stop. Another success story! Thank you TGuard!

    This worked better than anything else we tried to get my daughter to stop sucking her fingers. Overall it took around 3-4 months. She kicked the daytime habit sooner but it was harder for her to stop at night in her sleep. The only thing I didn’t like was that the wrist bands cut into her hand at night. We fixed this by using tied ribbons instead. She was disciplined enough not to untie them. Overall I am glad we bought this, it was the only thing that finally broke her habit.

  10. Laura

    My almost 3 year old has been sucking her index and middle fingers since she was an infant and now causing her front teeth to move forward. I didn’t want her to have jaw or bite problems later on so I gave the Aerofinger a try. The first night she wore it she instantly switched to her other hand. I had no other choice but to purchase a second Aerofinger. I am so glad I took the chance on these because 30 days later my daughter no longer sucks her fingers! I am so beyond relieved. If you are on the fence about these just take the plunge, you won’t regret it.
