Me = going to be an aunt!

Big news in my family right now - my dear sister and brother-in-law are now expecting a little baby boy or girl come March 16th!! As you can imagine, I’m quite thrilled at the prospect of having a little nephew or neice of my own :) . I’m also glad about the fact that I am now allowed to tell people of my great fortune... I’ve been keeping it secret for a good 6 weeks. You wont’ believe how often babies come up in conversation...
Oh happy me!! Now I just need to decide… Aunt Rachel? Auntie? Tante? ;) Any suggestions?
