Nosebleeds are common in children for the following four reasons:
- Frequent colds
- Nose picking (and other injuries to the nose)
- Dry air (especially in the wintertime)
- Allergies
The reason these situations lead to nosebleeds is because they all irritate the
lining of the nasal septum (this is the name of the cartilage that separates
your nostrils).
The best way to prevent nosebleeds is to deal with the underlying condition. In
addition, it helps to moisturize the lining of the nasal septum by rubbing a
thin coating of petroleum jelly along the septum. (Some of my ear, nose, and
throat colleagues prefer saline gel products that can be purchased without a
prescription.) Most kids prefer to do this themselves because they do not want
anyone “messing with” their nose. If your child falls into this category, show
her how to do this by demonstrating the technique on yourself: the product can
be applied with a cotton swab or with an index finger. Apply the lubricant once
or twice a day as needed to keep the problem under control. If your child
continues to get nosebleeds, discuss the situation with your doctor.
