My 3 year old has been sick since Sunday. She started with a cough and runny nose and now has had a fever since Sunday night. I’ve been alternating Advil and Tylenol which does bring the fevers down within about 2 hours and they’ll stay down for about 7 hours then spike right back up to 103. Last night I thought we were done with this as she all of a sudden was running around the house playing and acting like her normal self. But then at about 2am she wakes up screaming and burning up fast. She’s never had a fever this long before. 2 days max but we’re into day 3 now and I’m am extremely stressed out.
