Between Kim, Kourtney, Khloé, and Kylie, we've seen a lot of Kardashian pregnancies over the years … and that means a lot of baby bumps. But right now, it's Kourtney Kardashian's turn. She and husband Travis Barker are expecting a baby boy, and after watching their infertility journey on The Kardashians, it's hard not to be over the moon for them. They both seem so excited!
Of course, Kourtney's style has evolved a bit since she started getting closer with Travis — as Kim would put it, she's very "rock on" these days. That means that now that she's pregnant with her fourth child, she's also sporting a very different type of maternity style than she was when she was carrying Mason, Penelope, or Reign.
It was only earlier this summer that Kourtney announced her pregnancy, but since then, she's been sharing so many bump photos along the way. Here are all of our favorites so far.

The Very First Bump
Kourtney debuted her baby bump at the same time she shared the news that she's expecting a baby — at the Blink-182 concert when she announced her pregnancy! She was already showing in the black bodysuit she wore to hold up that "Travis, I'm pregnant," sign. Wonder what her baby will think of this stunt when they grow up and figure out how cool their parents are?
Drumming Away
Was anyone else absolutely not surprised that the first bump photo that Kourtney shared after her pregnancy announcement involved Travis and a pair of drumsticks? This was taken the same night that she filmed the video at the Blink-182 concert, and as always, these two look so in love.
Summer Bump

Kourtney included this photo in a summer photo dump that she shared on Instagram back in June – complete with a glimpse of the totally over-the-top vacation home that she stayed in. For her first bikini bump photo, she really did not hold back!
The Gender Reveal
The way Kourtney and Travis revealed the gender of their baby (Spoiler alert: It's a boy) couldn't possibly have fit their relationship better. Kourtney sat on Travis' lap while he got the drumroll going, only for blue confetti to explode all around them.
Baby Boy Blue
Kourtney couldn't have possibly worn a more perfect outfit for her gender reveal day — are we sure she didn't already know?! She wore this sheer blue turtleneck dress the day her friends and family found out she was having a boy, and she looked ethereal in it.

Girls' Trip
A hot pink bikini is the perfect swimwear for a girls' trip (and she even took BFF Addison Rae along for the ride). Kourtney seemed to be living her best life in that pink bikini — undoubtedly a nice time to relax while doing the difficult job of growing a baby!
Artsy Mirror Pic
Kourtney gives us the vibes that she loves an artsy photo, so this one doesn't surprise us at all. In an all-black body con dress, she's showing off her bump big time, and we're loving the hair extensions on her. Work that long ponytail!
Elevator Bump

Speaking of mirror pics … here's another one. This time, though, she took advantage of a mirror that was found inside an elevator, with her belly peeking out just below her T-shirt. Her bump has been growing crazy fast. Maybe she's closer to her due date than we think.
Quit Pit Stop

Another addition to Kourtney's mirror bump photo series, this time in a public restroom (a place we didn't think the Kardashians spent much time). Truly, with a bump this good, is she really supposed to just walk by the mirror and not snap a pic? The sunglasses really take this to the next level.
Saying Aloha
Kourtney took Penelope and some of her friends to Hawaii to celebrate her daughter's birthday in July, which really gave her the perfect back drop for more bump photos, including this totally Barbie core bikini look. So cute!

Beach Lounges
During her Hawaiian getaway, Kourtney shared these photos that have us convinced Hawaii is the ideal location for a babymoon. It looks like she was totally at peace, whether in the water or the waves. This is the kind of relaxation we all need.
Mama in Charge
Kourtney's giving us major boss vibes in this photo. Though we do have some questions about the logistics of a jumpsuit like this while pregnant (considering how frequently bathroom trips become during this magical time) we can't deny that she looks good.
Mom & Birthday Girl

Considering that Penelope is about to become a big sister (again), it's good to see that they had so much fun on their Hawaii trip — after all, everything is about to change in their household! It looks like they had the best time, and Kourtney couldn't help taking another opportunity to show off her bump in this mesh top.
Fashionable Bump

The next time someone tries to tell you that you can't be fashion forward while wearing maternity looks, show them this photo to prove them wrong. The sheer top? The leather pants? The spiky handbag? This style really is giving us everything.
