It's the little things, really. The tag in a shirt, the seam of a sock. The tilt of the head for a shampoo. The sway of a swing, the whirl of a fan. The modest effort needed to lift a spoon, push a pencil, close a door. The small effort required to tolerate bright lights, sharp flavors, strong smells. They seem like such little things to you. How can they be such a big deal for your child?
