Baby Thank-You Cards

Hello!  I decided to be ahead of the game, got inspired, and made some thank you cards for when our baby is born.  We are decorating the nursery in yellow, gray, and white, hence the colors for the card.  I wanted to do something really simple in case I didn't make enough and had to do more later.  Everything here is Stampin' Up (well, except the card stock, which is from Michael's).  So yeah, question for all you moms out there -- how many thank you cards did you go through after your baby was born?  <3 JEM
