Sam is learning those little lessons that make his life easier and more ordered. Sometimes he'll point to himself and say "Mommy's boy, Daddy's boy, Malcom's boy, Sam's boy" showing a good sense of family identity. Sometimes he'll snatch the computer mouse away if I'm not paying attention to him, showing good problem solving skills.
My favorite though is when he mutters, "It's okay Sam," to himself when he's disturbed by something. We first noticed it after putting him to bed one night when his sobs stopped apruptly with the consoling self-advice: "It's okay Sam." We also hear it when he sneezes or almost falls off a chair. Today I heard it when he was perched atop the playground peering down the tallest slide. Apparently the occasion required some reassurance.
I'm glad he believes himself.
