Kendall Jenner and Kylie Jenner wished Caitlyn Jenner a happy Father's Day on Sunday by posting a series of throwback photos.
The family pictures showed the two Keeping Up With the Kardashians stars as children. They also showed many photos of Caitlyn before her transition, back when she was known as Bruce Jenner.
"Happy Father's Day to the soul that raised me," Kendall captioned a photo of her and her sister enjoying the great outdoors with their proud parent.
Kylie also wrote "So lucky to call you my dad" alongside one of her baby photos.
From red carpet events to Fourth of July celebrations, the photos captured several special family moments.
Take a look at the photos for a sweet trip down memory lane.
Last year, the three family members celebrated Father's Day with a little trip down Rodeo Drive. The outing came shortly after Caitlyn released The Secrets of My Life—a memoir that caused quite a bit of tension between her and the famous family.
"It's an adjustment. It's something you have to get used to," she said, referring to Caitlyn's transition. "But I've known since I was a kid. He never confirmed it to me, but I've known for a very long time. It's the same person. My dad says it herself sometimes, it's kind of like mourning the loss of someone, because it is. My dad is my dad, but he's not there physically anymore. But she lets me call her dad — that's the last little piece of dad I've got."
Caitlyn isn't the only one in the family who received a Father's Day message. Kylie also posted a sweet tribute to her boyfriend Travis Scott, who is the father of their child Stormi Webster.
"Happy Father's Day," she wrote with a heart emoji.
In addition, their sister Kim Kardashian posted a special message to her husband Kanye West.
"Happy Father's Day babe," she wrote. "Thanks for being such a good dad to our babies! Shout out to all of the amazing dads out there."
What's more, Khloe Kardashian posted a "happy father's day" message on Snapchat along with a photo of baby True Thompson. Plus, Kourtney Kardashian posted a throwback photo of her and her late father Robert Kardashian.
