Kylie Jenner and her big sister Khloe Kardashian have always bonded through sisterhood, but now they can say they have the opportunity to bond through motherhood as well.

After confirming the arrival of her daughter, Jenner received well wishes from her friends and family members, especially Khloe who is currently still expecting.

Khloe congratulated Kylie by sharing a photo of their matching baby bumps and reminisced on the months they spent as mothers-to-be.

"I'll miss you bumping along with me. Never in a million years did I think we would do this together but it's been that much more special because of it," the 33-year-old wrote.

Kylie Is A Mom

As in previous reports Jenner never publicly confirmed that she and Travis Scott were expecting, but on Sunday, Feb, 4 she revealed that she welcomed her daughter on Thursday, Feb. 1.

The lip kit creator took to Instagram to explain how her pregnancy has affected her life and thanked her family and friends for being supportive during this time.

"Pregnancy has been the most beautiful, empowering, and life-changing experience I've had in my entire life and I'm actually going to miss it. I appreciate my friends and especially my family for helping me make this special moment as private as we could," Jenner wrote.

The siblings went about their pregnancies similarly at first by keeping it a secret. However, rumors swirled that they were both expecting in September 2017.

Khloe waited until late December 2017 to confirm that she will welcome her first child with her boyfriend, Tristan Thompson.

As for Kylie she kept a low profile and never addressed the rumors until her daughter was born. She also shared a documentary-style video, which showed her pregnancy journey.

Khloe's Turn

Kylie might have waited until her daughter arrived to disclose the news, but Khloe has continued to keep her fans abreast of all the happenings surrounding her pregnancy via social media and her app.

Prior to Kylie's big reveal, Khloe took to Twitter to explain that she is now suffering from insomnia. The first-time mom shared a screenshot of a tip from a What To Expect pregnancy app.

Fans immediately responded to Khloe's tweet with suggestions for what she could do to help her sleep, and expectant moms like her also mentioned that they were experiencing insomnia as well. 

Luckily, Khloe doesn't have much longer to go as she will reportedly give birth to her boy or girl in April.
