LOL yeah they say that if your child sits other ways as well and alternates the way they sit then that is okay, My SIL did it all the time and has major problems with her knees now. the documentation kinda goes both ways , we just remind Erin to sit another way when we notice it, I figure I would rather try and get her to sit a different way then to risk the possibility of it affecting her later in life.
Here is a picture of her, you can really tell with her why they call it W sitting, she is on the more severe side of it, the closer the legs are in the milder it is and even sitting on your legs is a mild form of it.
