Is baby too hot or too cold? These safety thermometer cards ensure that an infant's room is not dangerously too hot or uncomfortably too cold. Although the cause of Sudden Infant Death Syndrome is not known. The Foundation for the Study of Infant Deaths (FSID) recommends that a child sleep in room temperatures between 61F (16C) to 68F (20C) with 65F (18C) being just right. Most adults find it difficult to judge room temperature and the FSID suggests the use of a simple room thermometer in rooms where your baby plays and sleeps. Place this cute Ollie the Elephant Nursery room thermometer on the wall near the baby's cot and you will always know if baby is sleeping in a room of the correct temperature. Our Ollie the Elephant Room Thermometer cards are printed A6 (Dimensions 105mm x150mm) and laminated for durability. Store out of reach of children, in a cool dry place away from sunlight and direct heat sources. The manufacturer holds the ISO world standard certificate for their thermometers.
