If the vibrations are fully waking up your child, you can reduce their intensity. Access the vibration settings in the app. Select the menu icon on the top left, select User Settings, and then select Adjust Vibration Level.
If the level's already set to the minimum, we recommend moving the Sleep Guardian further away from your child's torso or head. Other parents have found success by moving it toward the foot of the bed or off to the side of the bed.
After changing the intensity of the vibrations, if you don't see your child stir in bed or show any movement for a few nights, you may have reduced the vibrations too much and may need to increase the vibration strength.
