Winter is the peak of flu, and fever is also the most troublesome thing, especially for babies. 

The change in body temperature at this time is what we are most concerned about. 

Mercury thermometers are not safe, babies love to move around, and babies are repellent to measure anal temperature. Now hospitals use ear thermometers to measure body temperature. If you want to monitor your child's body temperature at home from time to time, in case you need it from time to time, it is the choice of almost every parent to prepare a thermometer that is easy to operate, fast and accurate.
