Nosebleeds occur in 30% of kids age 2-tween. The nasal mucosa is thin and the vasculature is rich. When a child is dehydrated, has nasal congestion, or picks the nose, the thin mucosa is not much protection. The noses starts bleeding. It’s usually at the tip of the nose (Keisselbach’s plexus). Parents should have the child lean over (not back), and put pressure constantly on the tip of the nose for 5-10 minute. If bleeding doesn’t stop after 2-3 attempts with this strategy, is when you might seek additional help. If nosebleeds are recurrent, putting petroleum jelly (i.e Vaseline) can be helpful. It is unusual to have nosebleeds in children less than 2, so be attuned to potential abuse.
