Scared :(

Bree

My poor baby (almost 2) woke up from his nap with a fever. He has no other symptoms. I have increased fluids and checked again it is now up to 102. I plan on monitoring him and if it gets any higher giving him some medication calling pediatrician. I would like his body to try and fight it. I just wonder why there are no other symptoms..? I'm so worried and scared. Any input? Ty!
