She loves being a mom! Kylie Jenner gave birth to a baby girl on Feb. 1 — and motherhood is everything the 20-year-old hoped it would be. “She’s been crying tears of joy. She can’t believe she’s a mom,” a source exclusively tells In Touch.

In fact, she can’t wait to get pregnant again ASAP. Kylie — who shares little Stormi with her boyfriend, rapper Travis Scott — is planning on adding to her brood. “This is the first of many babies for Kylie,” says the source. “Nobody would be surprised if she has another one next year!”

And while another insider calls her “a natural,” the source says the reality star asked momager Kris Jenner to move in to help take care of the baby, along with a baby nurse: “Kylie’s also very protective and a germ freak: She hired extra security and she doesn’t want strangers around the baby,” says the insider. “She’s only allowing best friend Jordyn Woods and immediate family to meet her daughter.”

That includes her dad, Caitlyn Jenner. “She visited with Kylie and the baby at Kylie’s house, but she wasn’t invited to the hospital for the birth,” says the source, acknowledging Caitlyn’s “glaring omission” from the short film about the pregnancy that Kylie posted on YouTube. “They talk, but the rest of the family doesn’t speak to Caitlyn.”

So what’s next for the makeup mogul, who spent five months out of the spotlight to keep her pregnancy a secret? Likely more of the same. “Kylie loved the time off and having privacy,” says the source, and the insider adds that “she’s planning to keep the baby out of the spotlight, though Kris is trying to convince her otherwise.”
