I have read over & over parents describing these breakthroughs. They take a therapy break, something clicks, and suddenly babies go from crawling to running in a week. I won't say that I haven't seen breakthroughs - my girl's independence in the pool this summer, her brother's reading last school year - but I've also walked the thousand steps with them to get to the edge of the cliff so it's never seemed magical [I promise there will be no baby bird leaving the nest metaphors].

You know what else she can do? Eat cereal. Not the dry Cheerios we've so abused her with she actually cries upon the sight (what kid doesn't like Cheerios?!) - but real cereal, in a bowl, with a spoon and milk, just like her brother. She's quite insistent about it actually, which eliminates frosted mini-wheats as a snack food forever - where the hell's the milk, mom?
Not spilled milk.
