Liam isn't walking or standing on his own yet and we are still working on his mastering sitting upright unsupported. However, the stander, mentioned in the last post, has worked wonders in strengthening the muscles that will help him to stand.
Initially during therapy, Liam's physical therapist would stand him up supported against a couch or ottoman and try to help him strengthen his leg muscles in that way, but Liam would just scream and cry. After three 15-minute sessions in the stander, we tried standing him up against the ottoman again and he instinctively pressed his heels into the ground and stood (with support) tall and proud as though this was what he was born to do. The stander has also helped him to enjoy his ExerSaucer more than ever, giving him more strength in his knees and ankles to bounce around.
