The Tommee Tippee Dream Maker has been developed with the help of sleep scientists. This sound and light sleep aid relaxes your baby, encourages them into a deep sleep and prolongs the length of their sleep. It mimics the natural sounds of the womb and encourages baby to fall asleep faster, deeper and for longer. Providing them with a comforting, familiar and more natural background noise. The soothing red light allows the production of melatonin and is minimally stimulating so won't disturb baby (or you).
