Children often sit in the shape of the letter W, and they can spend several hours in this position, while playing. Nevertheless, most people do not understand that that position can actually harm their children. However, every professional orthopedist will warn you not to allow your children to sit like this.
Namely, sitting like this can create inner hip rotation and creation of predisposition for development of serious orthopedic problems! Moreover, it causes improper bone development, as well as muscle deformation and contraction.
To be more specific, when in this position, the muscles of the torso cannot maintain body balance normally, as the effect of gravitation exceeds the basic body gravity center.
Therefore, it is of great importance to prevent this sitting in order to become a habit, as it is the easiest way to prevent any complications. That is why you should not allow your children to sit in this position. Instead, motivate them to sit with their legs straightened up, or maybe, crisscrossed, and you will significantly help their future body development.
