After a child walks with a walker it is easy to form a dependence on the walker, which is not conducive to the development of the correct walking posture of the child. When many children use walkers, the bones of the child’s lower limbs are not fully formed, usually within one year of age. This is when normal children should not learn to walk, walking too much can easily lead to deformities of the lower limb bones, such as the formation of X-leg, O-leg, or the formation of foot inversion or valgus, etc.. Because the child’s body will rely too much on a certain direction of the walker, it will lead to abnormalities in the bones of the child’s lower limbs. But the advantage of it is that children walking within the walker are not prone to falls and may be able to avoid the formation of many traumatic injuries. Therefore, the application of the child walker has equal pros and cons, but the principle is not to let the child learn to walk within a week of age.
