I use the kind that you swipe over the forehead. I bought it for my own kids, but it has come in really handy for the daycare as it is quick and easy to take their temperatures and nobody complains as you don't have to stick anything in their ears, mouths or armpits. It wasn't cheap, but for me it is worth it for ease of use and accuracy. In fact, when I feel someone has a fever and I have to check, all the other kids want me to check theirs too...so I do..it takes only seconds
