Nosebleeds can be a scary occurrence, but are usually not dangerous. The medical term for nosebleed is epistaxis. They are fairly common in children, especially in dry climates or during the winter months when dry heat inside homes and buildings can cause drying inside the nose. Many times, children outgrow the tendency for nosebleeds during their teenage years.
The front part of the nose contains many fragile blood vessels that can be damaged easily. Most nosebleeds in children occur in the front part of the nose close to the nostrils.
