I know all toddlers go through chucking food and dishes on the floor, but it still drives me nuts.
One website I looked at said something to the effect of, "Lighten up! What's a little scrambled egg on the floor. He's just checking things out! He's a little scientist exploring gravity!"
Yeah, right, "little scientist". Checking out the parents is what they're doing, seeing how they'll react (Fun Fact: apparently a big reaction is delightful!) Don't underestimate your kid just because he/she's not two yet. They're smart. They know what they're doing. They'll look you right in the eye while they're doing it, too.
And I'm sure during these experiments the "little scientists" have a whiteboard somewhere with a tally on it.
"Toddler, 49. Parents, 0."
