Nicky Hilton Shares Advice She Gave Sister Paris Hilton On Motherhood

Sisterly advice? Loves it!

Nicky Hilton recently shared the words of wisdom she gave Paris Hilton about the first year of motherhood following the birth of baby Phoenix Barron Hilton Reum.

"My advice always is to not miss the small moments," the 365 Style author exclusively told E! News May 18 at an event in New York for the Smirnoff ICE Relaunch Tour. "There's such a short window that they're so small, and new things are happening every day. Like, Paris always says her son looks different every day."

Phoenix, 4 months, is Paris and husband Carter Reum's first child together, with the couple privately welcoming the little one via surrogate in January. 

"She is so happy. She's so content," Nicky shared. "I was just over there last week and just hanging out in the nursery with her and her son, and she's so complete is the word I'd use."

The fashion designer has three children of her own with husband James Rothschild: Lily-Grace Victoria Rothschild, 6; Teddy Marilyn Rothschild, 5, and a 10-month-old baby boy whose name has yet to be revealed.
