So P was fine all day. We got home, he had lunch, took a nap, woke up in a good mood. He felt warm when he woke up from his nap, but he often does, so I didn't think anything of it. But he still felt warm a couple hours later, so I took his temp. 102.7! I have no idea where this even came from. He seems to be ok with eating, peeing, pooping, etc. This just came out of nowhere! He was also acting pretty normal, until later and he seemed pretty tired and wanted to go to bed. I actually just put him down because I wanted to give the Tylenol time to work and check his temp one more time. It is down to 102.3. I also got pedialyte for him even though he is eating and drinking ok. I thought with the fever it was probably best to give him some. Hopefully this is nothing serious! Any ideas?
