Our expert says:
Your children require an ENT examination to try an establish a cause for the nosebleeds. Generally the problem is due to allergies, or prominent, enlarged bloodvessels in the front of the nose. In hot weather the bloodvessels enlarge, and are more prone to breaking and therefore bleeding. Unfortunately children scratch their noses, often without being aware, causing the bleeding, (ie. in their sleep).
This can be managed with ointment, and in more severe cases one could cauterise the nasal passage.
An examination is first needed to exclude other causes, such as a growth in the nose, or a general underlying bleeding disorder. These causes are indeed very rare. Nosebleeds in children are quite common.
