Kylie Jenner finally ended months of rampant speculation by announcing that she had indeed given birth to her first child, a daughter, with boyfriend Travis Scott. Kylie repeatedly dodged the limelight while pregnant, shying away from cameras, public events, and from appearing on her family's hit reality show Keeping Up with the Kardashians

In the wake of her very public revelation, her family has begun to show an outpouring of love for their youngest sibling, taking to social media to express their excitement over the most special milestone in Jenner's life thus far. Sister Khloe Kardashian posted an image of the two expectant mothers-to-be cradling their round bellies (Kylie was much farther along in her pregnancy than Khloe in the Instagram post.)

Now it's Kim Kardashian's turn to share her own excitement over the arrival of Jenner's first bundle of joy. Taking to her app, Kim shared a very kind note that expresses her utmost support for her sister. She begins by writing "Mommy Kylie!!! You did it!!! I'm so incredibly proud of the woman you have grown up to be and I know that you are going to be the best mom to your new baby girl!"

Continuing onwards, Kim notes how their "girls are two weeks apart and I can’t wait for them to be besties! I am so proud that you do what you want to do and live your life the way you want, you will pass down all of those amazing qualities to your baby girl. You were made to be a mom! I love you!"
