Not found my 2nd son does this at the moment, but my 1st son did this when he was about 9 months to 1 year old. He banged his head against the wall again and again. I noticed that he should feel interested of the action and feeling, so he did it again and again, but he won't bang his head against the wall hardly. I think he was learning and it is funning. The kids are smart; they won't hurt themself. Just like biting, he won't bite himself; he only will bite the others. My 2nd son bit my belly last night. He is toothing!
