So, have you told Casper about the sibling yet? We haven't, and I'm not sure how to go about it. But we need to make a decision about it in the next several weeks, thanks to the ultrasound appointment: our doctors only do ultrasounds at their local office in the afternoons -- if we want a morning appointment, we've got to drive half an hour to their other office. And Chuckles only has preschool in the morning. So we may fill her in on the new development and let her come along to the ultrasound (and of course tell the tech to save any scary stuff to discuss w/o her present).

I don't know. That might be weird. But we know she's already on board with the basic "babies in tummies" idea because they've talked about it at school, so we wouldn't be starting completely from scratch.
