This mobile app, sponsored by Guy's and St Thomas' NHS Foundation Trust, gives parents tailored advice, such as dealing with night terrors or up-all-night teens, based on their sleeping patterns. It has been designed in a dark and orange palette to minimise the amount of blue light emitted - which is the wavelength of light that most disrupts sleep.
Won't go to bed? Waking during the night? Night terrors? Is controlled crying safe?
