Matt (to Jackson): Are you going to be a good big brother?
Jackson: Yeah, I know a lot about babies.
Matt: What do you know about babies?
Jackson: I know lots of things: diapers, bottles, and one more thing, food!
The rest of the conversation continued with Matt telling Jackson more about babies' habits (eating, sitting, crying, not doing much). Hey, if we're going to prepare him, we might as well let him know that the baby won't be playing with him right away.
