Calabasas, California – It was a Mother's Day to remember for the Kardashian-Jenner crew – with dedications from the ladies' partners amidst swirling rumors, a birthday thrown in, and outrageous gifts galore.

The Kardashian-Jenners flooded Instagram with throwback family photos on Sunday in celebration of Mother's Day, which also happened to fall on the second birthday of Kim Kardashian's youngest child, Pslam.

"He turns 2 today on Mother’s Day," Kim said as she shared photos of her baby boy. "You have brought such calmness and evenness into all of our lives...You really are the joy of our crew!"

The sisters sent each other flowers and shared photo tributes to their children and family matriarch Kris Jenner. The mama bear called attention to bone marrow donations as she highlighted the dozens of flower gifts she received – even a large display from Caitlyn Jenner and her new partner!

The dads of the Kar-Jenner babies also honored the women with Instagram dedications. Travis Scott, who is rumored to be back together with Kylie Jenner, shared a poem with sweet photos dedicated to her and his daughter Stormi, which was met with lots of heart comments from the Kardashian sisters.

Tristan Thompson, who has been plagued with recent cheating allegations, also Instagrammed a simple "I love you" and "Happy Mother's Day" wish to Khloé Kardashian, with whom he shares daughter True.

Yet, the biggest display came from Travis Barker, who continued his hot and heavy fanfare for girlfriend Kourtney Kardashian by once again sending her a gigantic rose, peony, and moss-covered flower arrangement. The Mother's Day surprise filled the foyer of her house and matched a similar floral arrangement he gifted his girlfriend for her birthday last month.

Kourtney's ex Scott Disick sent an arrangement of roses to her mom Kris for Mother's Day– yet Kourtney did not share anything she got from him. The two have reportedly been keeping their distance since Kourtney's romance with Travis began to heat up.

Kanye West was radio silent about Kim amidst their split, but she shared her meaningful gifts from their children.

On her Insta Story, she explained that each of her four kids created a customized bottle of perfume for her– personally choosing the scent's name, ingredients, and bottle design of drawings and photos.

The family started their Mother's Day Sunday bright and early with a group workout on a new toy – a customized Street Strider exercise bike with each of their names personalized on the back.

The sisters baked Armenian bishi pancakes together as Kim showed off some homemade cookies in the afternoon, which they called "a tradition."

Then their get together included a cheeky present from Kris, who gave each of her daughters a Chanel-bow wrapped gift box tagged with a funny crying photo of each of their faces.

"Because you guys have been a pain in the ass for 40 something years," Kris joked.

Kim had some playful words back to her mom, who she said woke them up "through the intercom every day at 6:55am even on the weekends to just be up for no reason."

She continued, "You manage to raise 6 kids and make it look so easy. I now understand why vodka has been such a constant in your life."

In typical Kardashian style, the family celebrated the day away with their over-the-top fun.
