Nicky Hilton Rothschild is sharing the first glimpse at her baby boy!

On Thursday, the fashion designer, 38, shared two photos featuring her 2-week-old son, whose name has yet to be revealed. Nicky and husband James Rothschild are also parents to daughters Theodora "Teddy" Marilyn, 4, and Lily-Grace Victoria, 5½.

In one photo, the baby boy lays across Nicky's chest wearing the same Marie-Chantal Angel Wing Pointelle Sleepsuit that was featured in a 2021 Mother's day throwback photo Nicky posted on Instagram from when one of her girls was an infant.

"Baby bliss 🫧," she captioned the shot with her newborn.

The second photo, shared on her Instagram Story, shows Nicky holding the camera directly above herself, smiling as her baby boy's arms stretch up toward her.

Nicky's pregnancy was first revealed in January when a rep for the couple confirmed the news to PEOPLE exclusively.

"We are officially a party of 5!" she wrote. "Welcome to the world sweet boy. Mom, dad and big sisters could not be more smitten. 💙"

The couple hasn't shared the baby's date of birth or any further details.

In February 2020, Hilton Rothschild opened up to PEOPLE about the biggest lesson that she's learned from parenting her daughters: "Patience and being the best version of yourself."

She also got candid about one of the most challenging parts of motherhood.

"I think all moms suffer from mom guilt," she said at the time. "I think we could all do better at that and it's important to still do the things you love. Don't let your children completely take over your life. Navigate that balance and find that balance."

"Whenever I do work trips, I'll feel guilty about leaving the children," she said. "But at the same time, I think it's also setting a good example for your children about working on what you're passionate about. I want to lead by example."
