Kylie Jenner was "leaning" on Kris Jenner and Kim Kardashian West when she found out she was pregnant.
The 20-year-old reality star is reportedly expecting her first child with her boyfriend Travis Scott, and when she discovered the news, she turned to her mother and 36-year-old half-sister - who has kids North, four, and Saint, 21 months, with husband Kanye West - for support and advice on her future.
A source told Us Weekly magazine: "Kylie was leaning on Kim and Kris. And [they] talked through her decision-making process regarding moving forward with this pregnancy, having the baby and what she's going to do."
Although the 'Life of Kylie' star wanted advice from her relatives, her family were adamant the Kylie Cosmetics founder was going to make the final decision on her own, although she knew she had the full support of her mother on whatever she decided.
The insider continued: "Kris is so supportive and she knew this was a Kylie decision.
"They all wanted Kylie to make the decision for herself and to understand this is what it looks like, this is how your life will change, and Kylie gets that."
And Kylie's beau is "thrilled" by the news he is to become a father for the first time, even though it is rumoured the pregnancy was not planned.
A separate source previously said: "It definitely wasn't planned. [Kylie] had to decide if she was prepared, with or without his involvement."
Another insider added: "[Travis is] thrilled to become a dad."
And it has been reported Kylie decided to go ahead with the pregnancy because she believes having children has made the "lives better" of "everyone in her family".
Another source said: "Kylie's take is that for everyone in her family, children have only made their lives better."
