Mamma Lullaby Night light is a feature packed cot panel. Baby can be soothed to sleep at bedtime by the Mamma Lullaby as it projects a relaxing, soft, coloured light show to the rhythm of sweet classical melodies, new age melodies or gentle nature sounds. For a newborn baby, nothing is more reassuring than it's parent's voice, so the most exciting feature of the Mamma Lullaby Night light is that it allows you to record your voice and replay it for baby to help it sleep, or to reassure baby when it wakes up. Both of the above functions can be activated manually by buttons on the panel, or with the built in sound detector, which starts the panel automatically from the sounds of a waking baby. It can also be used very simply as a basic night light with either one constant light or changing soft multi coloured lights. Finally during the day, baby can be entertained with various fun sounds and activities on the panel front. 3 x AA 1.5 volt batteries not included.
