US Welcome Note Comments Privacy Statement Fat rolls on baby's legs don't match At my baby's most recent checkup, the nurse made a comment that the rolls of baby fat on the back of my child's legs did not match.
Hips are unique joints.
In fact, most of the ball is cartilage when the baby is first born. The socket of the hip joint is a rounded area that actually causes the cartilage of the ball to keep its round shape. Cartilage is a rather pliable tissue, so if the ball of the hip is not snug in the socket, it no longer stays spherical. Then, as the cartilage of the ball changes to become bone, the bone won't be spherical either. Hip joints that have square parts don't work too well.
