I don't like it when I have more than one at a time either. I feel like it violates any confidentiality of the student I'm focused on. Also, especially in the younger kids, they seem to "absorb" one another's symptoms. Kid #1 has a stomachache, and ends up with a peppermint, then kid #2 adds a "stomachache" to his initial complaint of cough so he can get one too. Kid #3 with a headache, starts coughing because he heard kid #2 coughing, etc. I find it's best to ask a quick "What are you here for today" and then have them wait outside the door on chairs, so there is some privacy and I can focus on each one individually. If they just want a band-aid, I either hand them one or tell them their teacher has band-aids. If teachers or aids accompany the kids, I hand them the thermometer if all they want is a temp check.
