Kim Kardashian is definitely keeping up with Kourtney Kardashian's growing family.

After the Kardashians star shared she and husband Travis Barker are expecting their first baby together, the SKIMS founder celebrated underneath the couple's sweet Instagram post June 17, commenting with a few emojis, including a heart and crying face emoji. Kim also re-shared the video of Kourtney's announcement to her Instagram Stories, writing, "Congrats!!! We're having a Kravis baby!!!"

The couple's latest addition serves as the seventh for their blended family. Travis is dad to kids Landon, 19, and Alabama, 17, with ex-wife Shanna Moakler, as well as stepdad to Atiana De La Hoya, 24. Meanwhile, Kourtney shares kids Mason, 13, Penelope, 10, and Reign, 8, with ex Scott Disick.

And Kim wasn't the only one that reacted to Kravis expanding their family, as his daughter Alabama also re-shared their video to her Instagram Stories as well, welcoming the newest addition to the Barker band by writing, "Baby #7."

In April 2022, Kim shared details on the couple's fertility journey, noting their wish to have a baby together.

"I think when you find love that you can't live without and there's still a chance," she said during an appearance on The Ellen DeGeneres Show at the time, "she's in her early 40s—I think they definitely want to see what life would be like with a baby."

As Kim noted, the pair opened up about every aspect of their process.

"They share their whole story and have been super open," she added. "I think people really will want to see how cute they are."

Kourtney herself has since shared that she Travis decided to take a break from the in vitro fertilization (IVF) process but expressed faith in their plans.

"We would love a baby more than anything," Kourtney said during the third season of The Kardashians. "But I just really believe in what God has in store for us. If that's a baby, then I believe that it will happen."

Read on to relive the couple's road to baby.

Months before she began dating Travis Barker, Kourtney Kardashian shared that she wanted to be pregnant again. When a follower asked if she was expecting, she responded, "No I wish." A few months later, she asked another fan on social media to "put the blessing out there."

The pair made their romance public soon after Valentine's Day.

Soon after getting engaged in October, they expressed interest in having a baby together and were hoping to be expecting by 2022, a source told E! News.

"They would love nothing more than to have a baby together," the source shared at the time. "Kourtney has always wanted another baby and never felt like she was done. Now that she's with Travis, she wants it even more." 

Travis had baby on the brain after they celebrated Halloween together—with Kourt dressing as Patricia Arquette's character, Alabama Whitman, from True Romance. He commented on a photo of her, "Our sons name would be Elvis."

The Poosh founder confirmed she and Travis were truly trying to get pregnant in a March 2022 teaser for The Kardashians' first season. "Travis and I want to have a baby," she said, as cameras captured them consulting medical professionals to start the in vitro fertilization (IVF) process.

Kourtney told Access Hollywood just how many little rockers she wants with Travis, gushing, "I would love two, in a dream world."

Kim Kardashian reflected on Kravis' hope to grow their family, telling Ellen DeGeneres, "I think when you find love that you can't live without and there's still a chance—she's in her early 40s—I think they definitely want to see what life would be like with a baby."

In an April episode of The Kardashians, Kourtney said IVF has been "awful" for her. "It hasn't been the most amazing experience," she said. "The medication that they've been giving me, they put me into menopause."

She told mom Kris Jenner that online comments speculating about her pregnancy really affect her. "Every single person on social media is always like, 'Kourtney's pregnant,'" she said. "'Kourtney's gained so much weight.' And I'm like, it's so rude to comment on people when you have no idea what they're actually going through."

It's amore! Their families traveled from their home in Calabasas, Calif. to watch the couple get married in Italy.

The rocker duo shared that they were no longer going through the IVF process.

"We started an IVF journey, but I stopped," Kourtney told WSJ. Magazine at the time. "It was a lot. I took a break to just focus on our wedding and getting married."

Kourtney explained why parenting with the Blink-182 drummer just works so well, as she shares Mason, Penelope and Reign Disick with ex Scott Disick, while Travis shares Landon and Alabama Barker with ex Shanna Moakler and is also stepdad to Atiana De La Hoya.

"We have known each other and I have had my own relationship with his kids for, like, ten years," she told Today. "It does make it really easy. We all just know each other and each other's intentions."

She added, "I came from a blended family... We have experience."

When one fan commented, "Wait a minute, did I miss that she's pregnant?" on Kourtney's lingerie photo, the reality star replied, "Nope, but you're missing a woman's body."

Kourtney got candid on the negative effects of the fertility process, saying on the Not Skinny But Not Fat podcast, "It really took a toll on my health and mentally...The hormones. The medication. You have to get put to sleep every time. I know it's for so many people but it's just not for me."

As for why they tried it to begin with? "I felt like we kind of got pushed into doing IVF," she confessed. "If you look online, it says if you're over 40 go right away to an IVF doctor. So I felt a little bit pushed." 

Kourtney's new philosophy is that the "timing" will work out on its own: "I feel like if it's truly meant to be it will happen."

When a social media user asked if she was expecting, Kourtney responded that her appearance has changed due to "the after affects of IVF [sic]." She clapped back by saying, "I only acknowledge this comment because I do think it's important to know how IVF affects women's bodies and it's not spoken about much. Also are we still asking women if they're pregnant?"

On a May episode of The Kardashians, Kourtney shared that the spouses were "officially done" with IVF, noting that her eggs "didn't survive the thaw" and that none of them "made it" to an embryo. "People do it thinking that it's like a safety net and it's not."

"We would love a baby more than anything, but I just really believe in what God has in store for us," she said in a confessional. "If that's a baby, then I believe that it will happen. Being happy is most important, and being a good parent to my kids."

They were still determined to grow their family and were trying on their own, she revealed in a May 2023 Hulu episode.

In fact, she told Khloe Kardashian that they were tracking her cycle. "I know that I'm already late for you, but I am ovulating," she shared. "If you give us five minutes to go do something really fast...we'll be back."

Fifteen minutes later, she was back and saying it was a "record."

The couple shared that they're expecting! Kourtney pulled off a romantic stunt at a Blink-182 concert in June 2023, holding up a sign saying, "Travis I'm Pregnant" like in their 1999 music video "All The Small Things."
