Baking Snickerdoodles is dangerous work

Spark got this new helmet yesterday and wore it most of the day today. Here he and Grandma were making snickerdoodle cookies. Nothing happened during the baking that would warrant a helmet, the cookies were baked without incident. However, a few hours later he was running up the stairs, without his helmet on, tripped and hit his teeth on the top step which is wood. He had three that were bleeding but not loose. We thought perhaps he should start wearing a football helmet with a mouth guard!
