The effects of abnormal sitting and sleeping positions on young children
Dr Anthony Duffin

Children spend a lot of time playing inside, watching television, playing with computer games and a myriad of other toys that are easier to enjoy if they are able to utilise a floor space directly in front of them. They commonly frog sit or sit on their feet so they can play without reaching over their legs and feet.
They have greater flexibility than adults and can comfortably sit in these positions for extended periods, but both postures can interfere with the natural development of the bones in the leg and thigh.
