Time for some Siah stories, since he’s really coming into his own lately and coming up with new words and phrases all the time!  As an example —

The other day while he was playing outside at daycare, CiCi said to him, “C’mon, let’s go inside so I can change your diaper.” 
“No,” Siah shouted, and ran off to the deck.  (not unusual behavior for my strongly principled child).
After a minute, CiCi approached him again, “It’s time to change your diaper now.”
Standing on the deck defiantly, he responded, “I’m not having it, CiCi!”
