The Gro Company Gro Egg
Peace of mind at a glance - the innovative Gro-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 warm. The colours act as a reminder for you to cool or heat the room, to modify the baby's clothing, to use a different tog Grobag Baby Sleep Bag or for non-sleep bag users to alter the level of bedding.
