certainly nosebleeds aren't uncommon in children. a few drops every now and then isn't unusual. as to cause it's difficult to tell. if this happens more in the winter then i'd say it's perhaps due to dry air. you can try a cool air humidifier in the boy's bedroom to see if that helps. also a water-based lubricant like plain ky jelly applied sparingly to the nostril with a swab before bedtime can help. if the nosebleeds persist you may want to take the boy to his pediatrician for an evaluation. hope this helps!
