Beware the Jabberwock, my son!

"Beau" rarely makes a peep outside the house but when it's just "Pierre" & I, the boy jabbertalks nonstop.
For instance, he gets the hiccups a lot. He has taken up commenting on each one. [Hiccup] sigh [Hiccup] ahhh [Hiccup] oh! [Hiccup] YA!  Also, when he hears an ambulance go by outside he immediately says "oh!" (as if to alert me to the new noise) and freezes to listen.
