This evening I spent almost 30 minutes watching, and infrequently helping, Olive while she (1) carefully spread her crochet blanket from my Gramma Headley out on our playroom floor, (2) smoothed out any wrinkles or bumps, and (3) rolled it into a long tube.
Over and over and over again.
She is a great roller. I'm not sure that skill itself will be helpful in her life, but she does it carefully and slowly. And her dexterity at spreading out a piece of cloth (bigger and bigger over the past several weeks) and rolling it up is really increasing. Most of all she found a task that she enjoys and finds great satisfaction in completing. All of those things are very good.
