Newly-pregnant Lauren Conrad wants people to know that there are some things you should never say to a couple -- or a woman -- who is expecting.
The former Hills star, who is currently in her second trimester, took to her blog to discuss some of the major faux pas many people make when they're confronted with pregnancy.
"Most people only mean well when they are commenting on a pregnancy, but it’s one of those situations where it’s hard to know what to do or say," she wrote.
So what should you avoid doing according to the mom-to-be?
Rule #1 is to never ask a married couple when or if they're going to have kids.
"The decision to have children (both if and when), is an extremely personal one," the designer wrote. "And any questioning, pressure, or even hinting about it usually just makes the couple uncomfortable (and yes, this includes making comments on the Instagram of someone who is in the public eye!)."
From there, it's imperative one avoids asking if a woman is pregnant based on her shape or size.
"There’s no bigger blow to someone’s self-confidence and body image than asking them if they are pregnant when they are not," she reminded her readers.
Up next is refraining from commenting on a pregnant woman's weight gain.
Her point: "Women carry their pregnancy in all different ways, and can be self-conscious about it. Whether a woman is bigger than average or she’s not showing as much as she thought she would be, keep in mind that it can be a very sensitive subject."
Lastly, she said folks should never touch a woman's stomach without asking.
"It’s much more pleasant to have someone politely ask if it is OK before groping your midsection."
Lauren went on to add that, "A lot of these are things I didn’t even think about before entering into pregnancy myself, so I hope they shed some light on this sensitive topic for others who may not be in the know."
The author and her husband, William Tell, will welcome their first child this summer.
