DS is 20 months, and over the last few months I've noticed he quite often looks like he has a headache. He will kind of frown and rub his head above the eyebrows. He only does it for a few seconds and then seems to move on, but I'm not sure if I should be concerned? It's not daily but often enough for me to notice.

He doesn't have a fever and his appetite and energy are fine. No vomiting or anything like that. When I ask him if his head hurts he just says 'bruise' - when he's bumped his head at the park in the past we've commented that he might get a bruise - so I'm not sure whether to take this as a yes or a no!

Would you take him to the doctor?
