useful information

My daughter spent the morning surrounded by children. Not as in, "we have you surrounded, come out with your hands up!" although just as stimulating.
Books are always a hit with little children, and as my daughter read to her one year old nephew he listened attentively.
"A is for apple," my daughter announced, reading aloud.
"Oh," the little boy said, his voice edged with surprise.
"B is for ball," she continued.
"Oh," he responded, gratefully, as though she had given him a piece of very useful information.
And I suppose she had.
When you are one, it's all useful information.
