Sally is a 3-year-old female who presents after a head injury. She was at home jumping from the couch to the coffee table when she fell and struck the front of her head on the ground. The couch is about 1.5 feet off the ground. She cried initially but is now calm. She did not pass out and there was no vomiting. Her mom is very worried about the possibility of bleeding and is asking you if imaging is needed. What do you tell her?
