A three-year-old who displays the moodiness and attitude of a teenager. Also: three-nager
Though my 3-year-old is a little more calm, he demands lots of attention and is a bit of a drama king at times. I like to refer to him as my "threenager." You never really know what mood he's going to be in, and he asks "why" at least 100 times in a day.
