Of course I call them monkeys, funcky monkeys, chunky monkeys, silly monkeys
Hallie's nicknames: Baby Girl, Big Sister, Stinkybutt, Hallie Bananahead, Mustang Hallie (but you have to sing it like Mustang Sally), blondie,
Simon's nicknames: Simon Sassy Pants, Little Brother, Simon Samuel Foore O'Quinn (when he's in trouble), Cracker Jack, Tough Guy, LoveBug (but not in public, he would be embarrassed)
there are so many I'm surprised they actuall know their names
