At times Vance insists on feeding Tanner and if all three of us are in a good mood I'll let him. This is an idea of how things go:
Vance takes a long time getting settled in and Tanner lets him know that he is impatiently waiting.
Tanner opens his mouth as wide as he can because Vance's aim isn't always the best.
Vance literally stuffs Tanner's face with "Vance-size" bites and Tanner tries to make sure he gets it all in his mouth.
Vance thinks the mess on the floor and tray is "Gross."
Tanner about gets sick with the big spoonfuls of food.
Tanner then wants to feed himself.
