The innovative Gro-egg gently changes color helping you maintain whether baby's room temperature is to low, too high or just right, maintaining a safer sleep environment.

A yellow glow suggests a comfortable temperature for children to sleep in, while a blue glow suggests it's too cold and a red glow suggests it's too warm. The colors 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.
