Kim Kardashian shared a peek into her recent lakeside vacation alongside her daughter Chicago and her sister Kourtney Kardashian’s daughter Penelope Disick. 

Kim Kardashian knows middle daughters have to stick together. 

That’s why the SKIMS founder shared a super sweet glimpse into bonding time with her 8-year-old daughter Chicago and sister Kourtney Kardashian’s 14-year-old daughter Penelope. 

In the Instagram post shared July 30, Penelope proves she’s actually taking after Kim as she poses on a surf board alongside her aunt in a white bikini. Kim, meanwhile, is the yin to Penelope’s yang, sporting a black swimsuit paired with a bandana and sunglasses. 

Another photo from Kim’s dump is a sweet selfie of the duo alongside Chicago, who sits on her elder cousin’s lap as they all smile for the camera. 

Kim, 45, proved the Kardashian family can’t get enough of their vacation spot in Idaho, quipping in the caption, “Lakemaxxing.”

Kim—mom to Chicago, as well as North, 13, Saint, 10 and Psalm, 7 with ex Kanye West—and Penelope’s summertime adventure comes less than a month after Penelope lavishly celebrated her 14th birthday. 

Penelope’s mom Kourtney—who shares the 14-year-old, and sons Mason, 16, and Reign, 11, with ex Scott Disick, as well as Rocky Thirteen, 2, with husband Travis Barker—shared a glimpse into the festivities which included heart-shaped pancakes, balloons and colorful doughnuts. 

Meanwhile, Kris Jenner emphasized she was floored by her granddaughter’s latest milestone. 

“I can’t believe how quickly time has flown and what an incredible young lady you are!!” Kris mused in an Instagram shoutout July 8. “You are so smart, thoughtful, creative, confident, funny, and so caring, and I couldn’t be more proud of you.”

The 70-year-old noted that watching Penelope, who is among her eldest grandchildren, grow up has been “one of the greatest blessings of my life, and I treasure every moment we spend together.”

“I can’t wait to see what exciting adventures are ahead for you,” Kris added. “Happy birthday, P! I love you beyond measure and thank God for you every single day.”
