The Kylie Cosmetics creator, 24, gave birth to the pair's son last month, making the on-and-off pair officially parents-of-two. (They already share 4-year-old daughter, Stormi Webster.)
But Jenner recently revealed that her postpartum recovery hasn't been as easy as the first time around, sharing with her Instagram followers that she has been struggling a bit.
Lucky for her, the Life of Kylie alum has been able to lean on Scott, who an insider claimed "has been so amazing for Kylie," per Hollywood Life.
"Even though he's not physically going through it himself, he is always there for Kylie," the source continued, noting that the "OUT WEST" rapper is always around "to listen to her, to be a friend, and let [Kylie] know she's not alone."
While Jenner is focusing on getting back to normal since giving birth, she has been able to see "what an amazing father" Scott is to their 4-year-old tot and brand new babe.
The reality star is "very thankful he's been by her side," the insider added.
Earlier this month, Jenner shared a candid video to her Instagram page to let her followers that the process after giving birth has had its ups and downs.
"I just want to say to my postpartum moms that postpartum has not been easy, it's very hard," she expressed in the clip. "This experience for me personally has been a lot harder than with my daughter."
"It's not easy, mentally, physically, spiritually, it's just crazy," she added.
After keeping things low-key on social media following her son's birth, Jenner told her 318 million Instagram followers that she "didn't want to just get back to life" without acknowledging her struggle. "I think we can go on the internet and it might look a lot easier for other people and put the pressure on us, but it hasn't been easy for me either."
"It's been hard. I didn't even think I'd make it to this workout today but I'm here and feeling better. So you've got this," she concluded in her video.
According to the publication, getting vulnerable with her followers was important to Jenner, as "it was something she initially deliberated with for a bit but ultimately felt like if she could help even one person who is also struggling, then that's all she could hope for."
Jenner's honesty has even had positive effects on her relationship with Scott, who has reportedly fallen "even more in love" with his baby mama than "he already was," a second source spilled to the outlet.
"She got real with him, and she confided in him," the insider continued. "Travis pushed her to do this because he knew how much of an impact she could make and how many lives she could save. They are working as a team now in the sense that they are devoting their lives to helping people recover. They have a shared mission, and it has given them greater purpose.”
