Before Wilco was born, I had no idea how Riley would react to having another kid around. She'd gotten kinda spoiled with attention after four years alone with us.
Now, five months into this sibling thing, it's safe to say she's loving it. Still. To say she adores her brother would be an understatement. Obsessed might be the better word choice.
But it's been amusing to see how fuzzy the line is between affection and torture. (And fortunately, the boy's a good sport.)
