No more worrying bath times - is the bath too hot for your baby? Be safe! The Duck bath thermometer card is a fast and reliable way to check for the correct temperature of baby's bath water. Just place in the water for a few seconds and if the water is the correct temperature the duck thermometer shows a tick, as shown in the image. It will also show when the water is too cold or too warm. The Baby Bath Thermometers come in two designs: Duck, Hippo, Turtle and My Playful Kitty. Made from 500micron White Polypropylene Hold the thermometer completely into the water for 15 to 20 seconds or until the colours stop changing and read the panel that shows a tick on a green background. The margin of safe/comfortable water temperature lies around 37C. A bath thermometer is for guidance only and is not a substitute for parents' personally testing the water temperature before putting baby in the bath. Store away from sunlight and direct heat sources.
