The Real Housewives of Beverly Hills star announced she was pregnant in September, sharing later that month that the baby on the way would be a girl. She and her husband, security company CEO Edwin Arroyave, also share son Cruz, 5, and daughter Slate, 7. “When it comes to having kids, you can make all the plans you want, but once the baby comes, you just figure out what’s best for you both,” Mellencamp Arroyave, who is partnering with interior design service Modsy for her new nursery and playroom, tells PEOPLE exclusively. The soon-to-be mother of three and daughter of famed rocker John Mellencamp also says she’s “in such a different place” with her current pregnancy. “With Slate, I got pregnant via [intrauterine] insemination and with Cruz, it was through [in vitro fertilization], and it was multiple failed rounds of IVF. With both kids, I was on and off bedrest,” shares Mellencamp Arroyave, 38. “There was a lot of stress.” Never miss a story — sign up for PEOPLE’s free daily newsletter to stay up-to-date on the best of what PEOPLE has to offer, from juicy celebrity news to compelling human interest stories.

I’ve been able to be active the entire pregnancy,” she says. “It’s just been such a different experience.” To prepare for her baby girl, Mellencamp Arroyave has designed a brand new nursery and playroom for her kids, sharing photos of the spaces exclusively with PEOPLE. She broke down the process of designing the rooms with Modsy, noting that she’s “so obsessed” with the service. “You can go on and you fill out like a little style quiz,” she said. “So I submitted the pictures, I took the quiz and then they gave me two different options.” Claire Leahy Nursery for Teddi Mellencamp Arroyave’s daughter.

She has learned that she doesn’t need “every single little thing” to be in the nursery, though. More important than gadgets, she tells PEOPLE, is feeling comfortable in the space. “You just go in there and you feel relaxed and calm,” Mellencamp Arroyave says. “It just really set the tone for how I’m actually feeling and how I’m so excited and feeling ready for this baby to be here.” “I can’t wait to bring her in there and for her to start her little life,” she shares.
