And I can tell you all that it doesn't stop there. We have been married almost six years and have had two children and people still ask us all the time when we are having more.
Our first child died at birth due to medical malpractice and as you can imagine, pregnancy and childbirth are very scary prospects to us, even though we have gone through it again once already. The people who ask us all the time when we are having another all know about our experiences so basically people are just rude and nosy! The worst is when people ask when we are "having a second child" (we have already had a second child and they darn well know that) or when are going to give our living child a sibling. He already has a sibling, but he is in Heaven, and as if just giving your child a playmate is a good reason to have another baby!
Anyway, basically just saying that even if you all DO have a baby, the rude questions don't stop there! (including people asking if you've had a c-section or vaginal birth or if you had to have an episiotomy...don't know why everyone thinks these things are their business!)
