Our Ear Thermometer makes taking your child's temperature easy and convenient. It doesn't need a probe cover so you don't have to struggle with them or find that you don't have any just when you need one. It also doesn't require an uncomfortable "ear-tug" so your child will fuss less making it easier for you to take her temperature. And, clinical examinations show that temperature readings taken by ear thermometers are considered to be as accurate as oral readings. What will her heartbeat sound like? Your baby's heart beats 140-170 times a minute and will sound like a rapidly galloping horse. Her hiccups will sound like 2 rapid drumbeats, and her kicks will sound like soft thuds. You will also hear the nutrients passing through the placenta. This will have a whooshing sound. But don't just listen to these sounds share your joy.
