Is baby too hot or too cold? These safety thermometer cards use new liquid crystal technology to 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. Hang this cute giraffe nursery room thermometer near the baby's cot and you will always know if baby is sleeping in a room of the correct temperature. The New Single Colour Red Liquid Crystal thermometer ensures that the actual colour change is much easier to read, as the temperature is read at the top of the red line. Just check to see that there are 2 red bars and that will be the room temperature around 18C to 20C. They are easy to use with full instructions on the rear of the product and are a new alternative to the standard multi-colour strips. Our Giraffe Thermometer cards are printed on laminated card for durability (Dimensions 90mm x 205mm). 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.
