Scene: The morning after Anne's sleepover at the breakfast table.
Me: I heard Benjamin was sick. Is he feeling better?
Anne: I don't know. (pause) Yeah, he's feeling better.
Ella: Did he go to the doctor Anne?
Ella: Did he get a sticker?
Ella: Oh. That's a problem.
 "I don't know" seems to be the toddler default answer if one isn't on the tip of the tongue. This is a frequent type of exchange with Ella: "Do you remember what kind of car she has?" "Yeah." "What color was it?" "I don't know." "What color was the car?" "Umm... blue." "Right!"
