 “This is the age at which the characteristics of diplegia become more noticeable, mainly because, unlike other children at this age, the child with diplegia is not walking.” By the age of three, it is important for the child to be in a specialized school environment so the child can participate in physical therapy and learn social skills.Parents should not force the child to sit, crawl, or walk a certain way during this age period.Let the child do what's comfortable for them and allow the therapist to correct this problem.
