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 its too cold and a red glow suggests its too high.
