With the Grobag® Egg™ you can see at a glance if your baby's room is at the recommended temperature with this colour changing digital thermometer. Room temperature is vital in creating a safe sleeping environment for your baby and should be maintained at 16-20°C to help reduce the risk of cot death. The grobag® egg™ glows yellow if the room temperature is within recommended guidelines (16-20°C). If the room temperature is outside this range, it acts as a reminder for you to take action to cool or heat the room, or to adjust the baby’s bedding or clothing.Every baby’s home should have a grobag® egg™ room thermometer and it is ideal for use with grobag® baby sleeping bags to help you to monitor the temperature of the room where you baby is sleeping.Customer review from Mrs S Billingsley - LiverpoolAs a childminder it essential that I provide a comfortable environment for the children tht I care for in my home, so having the room at an appropriate temperature is crucial. The Grobag Egg allows you to moniter the temperature of any room with its easily read, highly visible LED screen. The egg glows according to whether the heat is insufficient- blue, just right- yellow/ orange, or too hot- red which means you can see it from almost any part of the room- no more straining up to see a very small line barely visible. Fantastic. Worth every penny.
