My 19 month old son is bleeding from nose.

See the doctor: Your son needs to be examined by a physician to determine the cause of the bleeding.

When, how often: The most common scene i face is the kid who awoke with a bloody pillow or sheets & tinge of blood on his/her nose. This is often related to itchiness felt when a kid suffers from nasal irritants or allergies & rubs his/her face into the pillow in their sleep. Tender capillaries in the nose leak & stop.The doc can verify the location of the bleeding. Nasal saline jell applied before bed often helps.
