My friend’s son, “Ozzy,” turned one yesterday. One of the fun things we adults did at his birthday party was chuckle at the way Ozzy crawls. He keeps his left knee bent as if sitting criss-cross-applesauce (or whatever parents are calling it these days; what we called it in my day is probably inappropriate on this message board), and shimmies along using his right leg, and his arms. It’s as if his left knee is injured or defective.
But his left knee seems to be fine when Ozzy stands, climbs, or takes a few steps. Only when he’s crawling does his left knee go bad.
Should my son be mentioning this to Ozzy’s pediatrician?
