If you are a parent of toddler, taking temperature can become a tricky task. While mercury thermometers may be quite accurate, they are not always safe to use for toddler, especially for those under 3 year olds.
The digital thermometers do not take so much time to get the results, but you should rely on the batteries to get the accurate results. Modern versions such as pacifier thermometer or forehead thermometer may also become a quick and easy option to take your toddler's temperature. The ear thermometer requires only several seconds to get the result and is a reliable method but may be costly.
