We're hopefully going to find out what we're having on Wednesday (and hopefully that everything looks ok). With Natalie, we found out right before we flew home for Christmas so we wrapped up a little dress for both sets of parents and had them open it up as our way of telling them what we're having. I'd like to do something similar this time; however, we won't be back in the Midwest so we have to tell them via webcam.
If we have a boy, I was going to have Natalie show them her new toy -- a baseball.
Any suggestions on what I should do if we're having another girl? Matching dolls? (DH wasn't so into that one).
