It's amazing to see North West growing up so quickly!

After turning 1 year old last month on June 15, the celebrity baby hit another milestone in her short life on Wednesday when she took her first steps.

According to her proud mother, Kim Kardashian West, the adorable tot walked for the very first time after completing a swimming lesson. To celebrate the big moment, her dad, Kanye West, snapped a photo of his two favorite girls.

"Our baby girl finished one week of swimming lessons today then took her 1st steps right when she got out of the pool!!!!," wrote Kardashian as a caption on the photo posted on Instagram, which shows her kissing baby Nori who is wrapped in a yellow towel. "Mommy & Daddy are so proud of you!!!!" she said, adding, "Photo cred: Daddy."

According to inside sources, Nori is a natural born swimmer and "is doing a great job" when it comes to swimming, an insider told Us Weekly.

The West family has been spending time with Joe Francis, the creator of "Girls Gone Wild" in Punta Mita, Mexico, while the rapper works on his new album.

Earlier this month, the 33-year-old reality star shared a touching pic of herself giving Nori a goodnight kiss on Instagram. She captioned the black-and-white photo, writing, "Night!"

The wife of Kanye West also recently opened up to parenting blog Romy and The Bunnies about the joys of motherhood.

"I love being a mom! It's the most rewarding feeling! I really love every phase! Just the way my daughter laughs with me, all of the small things in life you appreciate," Kardashian said.

Despite being a mother for just a little over a year, Kardashian also used the interview to give advice to other working mothers.

"It is an adjustment trying to balance a career and motherhood, for sure, but the key is to prioritize," she said. "You become more selective and work on projects that are so meaningful because you want every other waking moment spent with your family. You have to remember, though, to make time for yourself. If you feel good, you will be happy in your career and family life, and everyone is happy!"
