In order to get Allan motivated to stretch and reach, we have been setting up the blocks (which he loves to knock over) to the left, right and center, but just out of reach. Little guys with breathing issues don't like to constrict their lungs by bending over or twisting very far.
This works very well with Allan, but he does get irritated from time-to-time.
Of course, we have to do a lot of this after Griff is in bed because he will butt in to knock over the blocks or move them in to the other room. Away from Allan, in other words.
