My 9 month old son keeps grabbing his head like an adult would who has a headache, should i be concerned or is this normal?

Pain?: If he has been doing this a long time and doesn't seem to be in pain than I would not worry about it. However, if this is a new behavior I would at the very least have it checked out. It could be an ear infection or he could really have a headache. Also if he has other symptoms with it, such as head tilt, ocular changes, etc I would have it check out immediately.
