Little Boy Blue

Today my youngest refuses to believe me when I tell him he has a blue nose. He also refuses to let me near him to wash it off. Ah, three! Such a fun age. They love to tell you about the "terrible twos" but nobody seems to warn you about three...

[J-La]

Is there any good alliteration for three? The threatening threes? The "I know what I want and I don't have any self control yet" threes?
