Let's get this straight... there are certain things you can say and certain things you CAN'T say to pregnant women. Let's just say the list of things you can say is way shorter than the list of things you can't. Here is what you CAN say:
You look amazing!
Wow! Pregnancy REALLY agrees with you.
I hope I look as good as you when I'm pregnant.
The end. That's ALL you can say. I will say that this is completely unacceptable: You're ONLY six months along? You're big for six months.
Just thought I would share that advice with you. Chris knows what he can say, and is so great at making me feel beautiful, even though my face keeps getting fatter, day by day.
