2. Important Safety Information
Please read all directions carefully before using the TGuard AeroThumb. The device is safe when the correct size is used and it is applied properly.
- The device MUST be removed daily.
- Inspect the skin underneath and around the device daily for any signs of irritation or chafing.

3. Sizing Guide
Selecting the correct size is crucial for the effectiveness and comfort of the AeroThumb. The most accurate way to determine the appropriate size is by the child's weight, rather than age alone.

Image 2: TGuard AeroThumb Sizing Chart. This chart illustrates three sizes: Small (S) for ages 2-4, under 40 lbs; Medium (M) for ages 5-6, 40-70 lbs; and Large (L) for ages 7+, over 70 lbs. The chart emphasizes that weight is the most accurate factor for sizing.
| Size | Recommended Age | Recommended Weight |
|---|---|---|
| Small | 2-4 years old | Under 40 lbs |
| Medium | 5-6 years old | 40-70 lbs |
| Large | 7+ years old | Over 70 lbs |

4. Setup and Application
Follow these steps to properly set up and apply the TGuard AeroThumb:
- Select the Correct Size: Ensure you are using the appropriate size AeroThumb based on the sizing guide.
- Prepare the Guard: Before first use, wash the AeroThumb guard with warm water and mild soap, then pat dry.
- Position the Guard: Place the AeroThumb over the child's thumb, ensuring it covers the entire thumb and extends slightly onto the hand. The wider part of the guard should be towards the wrist.
- Attach a Wristband: Choose one of the colorful wristbands. Thread it through the slots on the AeroThumb guard and around the child's wrist.
- Secure with InstaLock System: Use the InstaLock system to fasten the wristband securely. The fit should be snug enough to prevent removal but not so tight as to cause discomfort or restrict circulation. You should be able to slide one finger comfortably under the wristband.
- Check for Comfort: Ask the child if the guard feels comfortable and if they can move their fingers freely. Adjust as needed.

7. Troubleshooting
- Skin Irritation/Chafing: If you observe any redness, irritation, or chafing on the child's skin, remove the device immediately. Ensure the device is the correct size and not applied too tightly. Contact the manufacturer for further assistance.
- Device Removal by Child: If the child is able to remove the device, check the tightness of the wristband. The InstaLock system should provide a secure fit. Ensure the wristband is snug but not uncomfortable. Re-evaluate the sizing if the child consistently removes it.
- Lack of Progress: Consistent wear is essential. Ensure the device is worn during all typical thumb-sucking times. Reinforce positive behavior with the reward chart. If after the recommended 30-day period there is no significant change, consult with a pediatrician or dental professional.
