Kim Kardashian is now a mother of three. 

On Tuesday, the reality star took to her official website to announce the arrival of her daughter via surrogate. 

Now that baby West is finally here, the couple is helping their eldest children, North and Saint West adjust to life with their new sibling. 

Saint is just curious and not really that interested, but his older sister, North has already started to take on her role as big sister. 

"North is like a little mommy who wants to help and take care of her." A source told E! 

The new baby will definitely be a big adjustment for the Wests, but Kim is keeping their routines the same and gives them each a lot of one on one time. She doesn't want them to feel like anything has changed that they have a new sibling. 

According to sources, things aren't too crazy yet, because the baby sleeps majority of the day. 

As usual, Kim is enjoying her time out of the limelight and has been able to continue working out. On Tuesday, she took to her Snapchat to post a picture of her sneakers. 

"Quick workout while she sleeps," Kardashian captioned the photo. 

As for Kanye, he does the diaper changed and feedings. He also spends a lot of time with the kids. 

Kim Opens Up About Having A Surrogate 

As the couple adjusts to life with a third child, they are more than happy to finally have their baby girl. 

In June 2017, Kardashian stated that she and Kanye West have decided to use a surrogate to deliver their third child. 

On an episode of Keeping Up With the Kardashians, Kim revealed that she would be unable to carry another child due to preeclampsia and placenta accreta. 

Although both conditions were life threatening Kim took to her app to state that having a surrogate wasn't easier. 

"People assume it's better because you don't have to deal with the physical changes, pain or complications with delivery, but for me it was so hard to not carry my own child, especially after I carried North [West] and Saint [West[," Kardashian admitted

The makeup mogul also explained that she and Kanye instantly felt a connection with their daughter. It was as if she was with them the entire time. 

While the couple gets accustomed to having a new addition to their family, they have not revealed the name of the baby or a photo of her.
