Blue for too cold and red for too warm, and yellow is just right. Between 61 and 67 degrees Fahrisenheit is what Grobag Egg says is just right for your baby ideal sleeping room temperature range. We actually just like the easy way to tell if your room is too hot or too cold. Plus the Grobag Egg is a nice night light too.
