Now there is no need to disturb your baby to take her temperature or worry about having to continuously get up to check on her when shes sick. This Fever Monitor clips onto her diaper or pajamas and takes her temperature from the skins surface. The Fever Monitor beeps if her temperature spikes up one degree or if contact is lost with your babys skin. The beeps are loud enough to be picked up by your baby monitor but also soft enough not to wake up your sleeping baby. Now both you and your baby can get a good nights sleep!
