So I was looking for something for a friend and I saw this item. Apparently you can just clip it to a kid’s clothing so there is contact with the skin. Then you can check their temperature continuously. It will beep if it loses contact. One of the pictures I saw the kid had it clipped to the top of the diaper. The one annoying thing is it beeps if the temp goes up one degree. I don’t know if that is one single beep or what. But for less than $20 I think it is a good deal.
