Girls, who has a child flexible? My daughter is straight on the mat like sitting. Very flexible. Can put her leg above her head. Is this definitely a sign of dysplasia? Or maybe just such a feature in the child? We were at the orthopedist today, but only to x-ray on Monday. But damn I'm worried ? And we don't sit and crawl on all fours. Now she's trying to.
