The other funny thing that happened at big sister class is when we went to learn how to change the baby's diaper, there was poop in it!!!!! I wasn't quite expecting that (and neither was the instructor!). Apparently they put deli mustard in the diaper area, and you get a big surprise- more like a bio hazard if you thought it was real poop like I did!
Here are a couple of pictures from that day:

Sofia got to wear her big sister special outfit, and go to Chick-fil-A before hand. A real treat!
She's official!
