About 4 days ago, on holiday DS chase a chicken and brushed against a log burner, he's got a 5cm burn on his arm, at the time I ran it under cold water for as long as he'd sit still. He didn't cry so I left it be.
It had a blister over it until today when he's knocked it off and now it looks raw and sore.
Should I be putting anything on it at all or just leaving the air to get to it?
We were watching him btw, as I say he was after a chicken and slipped over and brushed the corner of the burner through the fire guard.
