Nightingale Vibrating Alarm
This effective vibrating product range will allow deaf parents to enjoy their sleep, confident that they will be woken if their baby cries. Conventional baby alarms, give both an audible and visual alert of a baby crying, which is usually an adequate indication during the day but at night is insufficient to wake up somebody who is deaf. The Connevans vibrating Nightingale baby alarm monitor simply plugs into the baby alarm, is placed under the pillow and vibrates when the baby cries.
