Children like to sit while doing things, and since they're learning, they tend to sit in whatever position is easiest and most convenient for them. Recently, people have noticed that one particular position, the go-to position for children, can actually be quite harmful to them in later life. This position is often referred to as the "W" sitting position, as the fanning out of the legs creates a "W."

This position is extremely common for children due to the stability it provides. Since their legs are fanned out, they are given a significant amount of support with the least amount of effort possible. Unfortunately, the "W" position comes with many potential problems. These problems include, but are not limited to, orthopedic problems, delayed development of postural control and stability, and delayed development of refined motor skills. 

The "W" pose places unnecessary amounts of stress on the knees and hips of the child, which is the reason for potential implications. Among these is the fact that children no longer need to reach as much, as well as a reduced ability to rotate their body.

The "W" position puts the child's spine into a curved position, which is also harmful. The stress from the position is pinpointed to certain areas, such as the hip abductors, hamstrings, internal rotators, and the heel cords. The tightening of these muscles as a result of this position can cause many postural or stability-related implications. Luckily, there are many alternative positions that can easily be taught to the child.
