K.S.
We took my daughter to an instacare one Saturday, and I was very surprised when they used a forehead thermometer; I had always understood them to be inaccurate? Maybe that is just my perception and obviously not fact since a Dr. office used one! Anyway, I have 20-m.o. twins and we have been using an ear thermometer since they were about the same age as your daughter; I did rectal up until then, but once they started on solid food I was done with that! We bought a Braun brand ear thermometer for about $25 at a local grocery store, and the probe covers are only $5 for 20 or 30 in a box. We have never had problems with it, and it is super fast and easy to use: perfect for toddlers. That would be my personal recommendation, but good luck with whatever you choose!
