Xander was sick for a couple of days. He was very crabby, lots of screaming and screeching. Now that he's better, he's much more of a joy to have around. I was saying how I was glad that the "other baby" was gone, and that Xander must have an evil twin. To which Jessica kept saying, "But Mom, it's the same baby." Then she offered to prove it by annoying him till he screeched again.
