This public service announcement has been brought to you by the makers of cheaply-made and ill-fitting maternity clothes.
Do not, I repeat, do not EVER say to a pregnant woman “wow! you’re getting BIG!” or “you must be getting HUGE!” It is tacky that you, a woman who has most likely never watched her weight and waistline balloon 30, 50, or even 70 pounds within 8 months or less, to say that to a woman who is MORE than aware that she is starting to gain satellite planets. And certainly don’t say that sort of thing to a woman who is anything less than your best girlfriend or closest sister.
To put it bluntly, even MEN know better than to let that sort of phrase fall out of their mouths within earshot of any woman they may think is pregnant.
This kind of behavior is even more insulting and unwanted than unauthorized tummy-touches.
So don’t do it. You could lose a limb.
