Hi, girls :) I want to do a fun poll — what do you call the baby in your belly? In the first weeks I called (them) Kolupunchyk, then we grew into a resident of Puzlyandiya, now Sladusik or Mister Shevelyushkin when he's very active :)) Am I the only one who can come up with a bunch of nicknames for the baby but can't choose a real name?!
