I've only taken LO's temp a couple of times and both times I took it under her arm. Now that she's in daycare I have a feeling I'll be taking it more regularly.

I am terrified of taking it rectally. She just wiggles around so much and I am worried about doing some sort of damage to her. Is taking it under the arm as accurate? That's how they do it at the ped's office, so I assume it is? How do you take your LO's temp?
