K.Q.
Hi. My daughter starting having bloody noses at age 10 months. She is now 4.5 years old. She constantly gets bloody noses from fit throwing and screaming. She gets her blood pressure so high from screaming and fit throwing that the blood pours out of her nose. At first, it worried me so much, but now it just seems to be a "routine". My advice is to try to calm her down before it gets to the point of bleeding. I would take her to the Dr. to make sure that her sinuses aren't inflamed though.
