Our son (14 mos. old) is finaly walking. He realized a few days ago that he could walk and actually get some place.
He took his first steps several months ago (at around 9 mos.), but he always wanted to crawl or be carried.
Our daughter took her first steps at 7 mos. and was walking at 9 mos. We thought our son would be at a similar level, but we were mistaken.
