My daughter, now six, used to get them a lot and still does now and again. They have very fragile little capillaries and, at least for mine, dry weather, heaters and ACs exacerbate the problem. My MIL who lives in Arizona gave her these little pre-gooed sticks called AYR. You can get them at Walgreens. They just swab it around in their nose and it moisturizes the nostril. When she is having problems we do it in the morning and night, and when I am consistent, they totally go away. It is worth a shot. I am a fan.
