In October, PEOPLE released an interview with Olivia Culpo's sisters Aurora and Sophia. Aurora Culpo called Olivia a "really loving mother" and talked about how she has been "very prepared" for her first pregnancy.

"I know she's going to be a really loving mother," Aurora said. "I know that she's going to be very prepared. I think she's going to have everything in place. Probably already picking out her children's preschool. At the moment she's probably already on the waitlist."

She added that Olivia is a "through and through perfectionist."

Sophia Culpo also revealed the small changes that she has started to notice inside Olivia's house. The former Miss USA's "house is no longer all white and beige" and has been redecorated with more cheerful colors. Sophia's statement reflects that Olivia and Christian McCaffrey started planning for their first pregnancy months ago.

Before announcing their first pregnancy, Culpo and McCaffrey celebrated their last Valentine's Day before becoming parents. She gave fans a sneak peek into her romantic celebrations via her Instagram account.
