My almost 7 year old has had 2 BIG nosebleeds the past two days, when in her room. I don't think it's particularly dry in the aptmt, but I ordered a cool mist humidifier that's coming tomorrow. Anybody know if this can be something serious I should worry about? Because you know, we don't have enough to worry about...But I've never had one, and it comes out like a faucet. thanks in advance!!
