This is one of my favorite items, with a thermometer in my baby's room I can easily see the temperature when I put my baby down for a nap, and know if I need to adjust the thermostat up or down. My little one sleeps best when the temperature is 69 to 71 degrees. If it's warmer, I know I need to run the fan, and if it's 73 or warmer he's going to be sweating, and he may need a cooler outfit and no sleeping sack. If it's 67 or colder, he's going to be cold, and I need to bump the heat up or make sure he's in a warmer outfit or swaddle. This clock can stand up on a shelf or hang on the wall. Let me know what you think.
