Addy had another awesome PT session today. The front wheels on the walker can swivel (to make steering easier, if somewhat precarious) or they can be locked (to make it easier to control, but only go in a straight line). So far we've generally had the wheels locked, but the therapist suggested unlocking the swivel wheels to help build up balance and coordination (and hopefully keep the foot-stomping to a minimum). She said to start with just one side unlocked and work up to both sides. By the end of the 30 minute session, Addy was scary good with both wheels unlocked.
