Having 3 children~and now 11 grandchildren I have used many thermometer's over the years. And they sure have come a long way since my children were little! As this is the first one that I have seen that has 3 Modes on it. You can take Body, Room, and Surface temperatures.
Your thermometer is ready to use as soon as you open the package as they even include the 2AA batteries that are needed. You just turn it on and take the temp~It also has a memory on it so you can store 32 recordings if needed. There is alarm if you need to take it every so many hours and a silent mode so if the little one is sleeping you will not disturb them. And when you are finished with the thermometer there is even a cute little drawstring bag to keep it in!
You can see this for yourself on Amazon right here
