Peace of mind at a glance - The innovative grobag egg changes colour to let you know at a glance whether the temperature of a room is too low, too high or just right, helping you maintain a safe sleeping environment for your baby.
As an added bonus it even works well as a gentle night light.
A yellow glow suggests a comfortable temperature for children to sleep in, whilst a blue glow suggests it's too cold and a red glow suggests it's too high.
