DS who is 2.5 got his flu shot on Monday morning I gave him Tylenol after just as a precautionary like always when they get shots. He was fine all day Mon all day yesterday but woke up this morning sneezing his head off I assumed it was his allergies so I gave him zyrtec. The Zyrtec didn't seem to help and he just kept sneezing and getting more and more stuffy. After who woke up from his nap he had a slight temp and was miserable. So I am wondering if it could be from the Flu shot or just his allergies??
Anyone had an experience like this?
