Riley gets Smiley Riley or Cryley Riley when he's upset. All the kids at FDC and my friends kids call him BabyRiley, we say Riley boy.
Erin's middle name is Kate so we call her Erin-Kate or Eeek or Eeekiepeneekie, she likes being called Princess!. Jess used to get JessicaMessica or Jessa or mouse but now she's far too mature!
