Paris Hilton Has Learned the Power of 'Saying No' Since Becoming Mom to Baby Son (Exclusive)

"He's my everything, so I always put him first," the proud mom tells PEOPLE exclusively of her 8-month-old son

Paris Hilton's new role as a mom has helped her learn the power of "saying no."

While chatting exclusively with PEOPLE about her upcoming "Be an Icon" kitchen and home collection with Walmart, the proud mom, 42, also opens up about how welcoming son Phoenix Barron with husband Carter Reum has given her new control over her life.

Noting how the multiple roles she plays — from singer to DJ, and author to businesswoman — are "definitely a lot to balance," Hilton says, "I always make Phoenix my first priority, and I've learned how to say no."

"I'm constantly saying no to things, because I just want to spend as much time with him as possible, and I just don't want to miss any of these special moments in his life and all these milestones," she continues.

"He's my everything, so I always put him first," Hilton adds of her 8-month-old son.

Hilton and Reum, 42, quietly welcomed their first child together on Jan. 16, 2023, via surrogate. The pair, who married in late 2021, kept the news of their baby boy to themselves for over a week.

Hilton later announced Phoenix's arrival eight days after his birth on Instagram with a close-up photo of her holding his hand, writing, "You are already loved beyond words 💙."

Hilton tells PEOPLE that she and Reum aren't alone in raising their little guy, either, as they have help from the "Stars Are Blind" singer's parents — mom Kathy Hilton and dad Rick Hilton.

"[My parents] are just so obsessed with him," Hilton says. "I'm always calling my mom and my sister [Nicky Hilton] for advice, and I'm really lucky that I'm so close with my family, so I have such a big support group."

Recently, the proud mom says she and her husband have been taking Phoenix to music classes, "which he loves," and have been giving him swimming lessons at their home.

"He's laughing, he's starting to sit up on his own, and we just started feeding him solid foods a few months ago," she continues. "So we're getting ready for him to start talking and walking and turning into a toddler."

Hilton also says she is so excited that she and her siblings are all having babies, welcoming a new generation into their famous family.

"It's just so cute to see this next generation of cousins," she says. "It reminds me of when my sister and I and our cousins were all growing up together."

Hilton adds: "Now, seeing all of them doing the same things, it's really cute."
