The Gro-egg is a unique colour-changing nursery thermometer that provides safety reassurance at a glance. It reminds you to change the baby's bedding, clothing, or adjust the room temperature if required; making it a nursery essential for new parents. This room thermometer is quite accurate and this is important for peace of mind, especially for mums who might need to move their baby into their own rooms at an early age. It gives off a warm, reddish glow if it detects that the room temperature is too hot, an orangey-yellow glow if it's warm, a soothing white glow if the temperature is fine, and a cool blue if the room is too cold. This Gro-egg also comes with a nice owl Gro-egg shell cover (which you would have to buy separately if you bought it at the shops). Get this at a bargain price!
