Things NOT to say to a Pregnant Woman

Although I'm starting to slow slightly, I'm amazed at what two people have said so far - one of whom was my darling husband: 

• "How's it feel to be getting fat?" 
• "You're getting huge" - Rob isn't very tactful with pregnant people since he recently told one of our friends who is pregnant "You're ginormous!" This poor girl also had people asking her if she was having twins when she was clearly only having one baby. Some people are so rude!!
• "You're so cute pregnant.. like a little elf!" - I'm guessing the connection is the height because Im' short and have been wearing flats lately, but really? You a) know elves and b) have seen them pregnant?

Didn't your moms ever tell you if you have nothing nice to say don't say anything at all? Granted pregnant women want to maintain a healthy weight gain but as long as we're having a healthy, normal baby who cares if you look like an elf or having twins?
