My 4 year old son seems to constantly get blood noses and they take at least 5 minutes to stop. He is really good with them but they are starting to worry me.

We have had 5 today. This is a lot but he has had a fever for the last 2 days so I am attributing it to that.

Has anyone else's child have such frequent nose bleeds and did they grow out of them? Do you think I should get it checked out at the GP? I have read the advice from the State Govt website and they said it was not unusual in some children but that doesn't make me feel better.
