No!

We knew the time would arrive - our little prince has found the correct use of the word "no". I've been expecting this since he was 10 months old, thinking that at any moment we'd hear that word thrown back at us.

Thankfully we haven't had any fits or tantrums, but Will started using "no" at lunch when I asked him to take a bite of mashed potatoes. He just turned his little head away from the spoon and gave me a curt little "no". Can the terrible twos begin at 20 months? I'm guessing the answer is "yes".
