A child's oral comfort device such as a teether or pacifier includes a strap, such as a wrist band, a housing removably attached to the strap, and a mouth portion fixed to the housing. The housing has a base and a removable cap. Inside the base of the housing is a printed circuit board having a sensor, a timer, a vibrator motor, a power source and a controller. When the infant applies pressure to the mouth portion, the sensor responds and sends a signal to the controller that activates the vibrator to vibrate the mouth portion for a predetermined time. The controller then prevents the vibrator from vibrating until the child reactivates the device with more pressure to start the vibrating cycle again. When the removable cap is attached, the housing and mouth portion are sealed preventing liquid from coming into contact with printed circuit board or its components. The strap, housing and mouth portion are constructed of silicone.
