"LK"

That's "LK" as in "Little Kate" also know as Katherine Thompson Hedges, baby sister, baby Kate, K-Tizzle and Kate, and formerly known as H4 or Stella.

Anyway, as you can see from the photo, I was pretty psyched when LK finally got here. I'm a bit preoccupied with "ere baby" and need to know where she is at all times. This is bad news for Moma and Dadu, because now that Jack Jack has a baby, I want one too - and don't think that cabbage patch you bought me is fooling anyone.
