My 9 month old son recently started crawling on all 4s. He was army crawling for a bit but will now crawl on all 4s from a seated position. I noticed right away that his left leg is always blended up under him and he drags it as he goes. Has anyone else seen this? I'm worried that asymmetrical crawling could mean there is a muscle or skeletal problem or could lead to one in the future. I've attached a picture below which kind of shows how his left leg is folded under.
Would appreciate any advice!!
