Me to Naomi: "Let me know if you need a little bit of help!"
GZ: "What? What? What?"
Me: "Naomi's getting dressed. Sometimes she can do it by herself, sometimes she needs a little help."
GZ: "When? When? When?" (He's been asking "what?" for a while; his new question is "when?"!)
Me: "When she's getting dressed."
GZ: "Okay! Room? Room? Room?"
(runs off to watch her get dressed)
