3. All two-year-olds all have a natural skill called the "Wet Noodle".
It's a very effective form of resistance that expends little energy (for them, I mean). You know, when it's time to (insert transition here) and they don't want to. When you try to pick them up, their bones suddenly liquefy, and it's like trying to lift a 30-pound garbage bag full of oatmeal.
The best is when they activate the "Wet Noodle" when you're trying to dress them. Ever tried to get a pair of pants on cooked spaghetti?
