Toddlers can’t walk down the stairs with alternating steps. They just can’t. While your kindergartener bounds down the stairs taking each step in stride (or several in one super-hero bound, as mine is prone to do), your toddler will cling to the wall or rail as she takes a careful step down with one foot, then brings the other foot to that same step to stand firmly before venturing down in that same slow, tentative manner for another (step together), then another (step together), then another (step together).
