Sisters Khloé and Kim Kardashian and mom Kris Jenner were in the room, too, tearing up at the arrival of the first member of the family's next generation. "Scott was filming it for our own purposes, like for a home movie," Mom shared years later. "The birth of my son was such a beautiful experience that I really wanted to share it with people because it was my child. I remember being so terrified to give birth because you see in movies everyone is screaming and it was so crazy and my experience was amazing. I just felt something in me wanted to share that with people." 02 of 08 Celebrating So Many Years Albert Michael/Startraks Then the only child of Kardashian and Disick, Mason held on to his mommy as they blew out the candles on his cowboy hat cake during his 2nd birthday celebration. The party kicked off a tradition of unique birthday themes the family has incorporated over the years; some of the most notable include "Kidchella," aliens, Fast and Furious and Fornite. 03 of 08 Cheering for Uncle Rob Disick sat front row on mom Kourtney Kardashian's lap cheering on uncle Rob during the season 13 semi-finals of Dancing with the Stars. The moment would not be complete without grandma Kris Jenner crying tears of joy for her son, who ended up winning second place. 04 of 08 Hanging with His Awesome Aunts Zoltan Moric/Feld Entertainment/Getty For three years, Disick enjoyed solely being spoiled by his aunts until sister Penelope came along in 2012. Check out the cheeks on the 3-year-old, who took a trip to the circus with aunties Kendall, Kim, Khloé and Kylie. Side note: Mason's teal slacks and mini loafers were totally influenced by his daddy's "Lord Disick" style phase. Oh, the memories. 05 of 08 Welcoming Two Little Sibs Kris Jenner/Instagtram What a special treat it is to share a birthday with your little bro! Mason held on to his youngest sibling Reign in this heart-melting post grandma Kris Jenner posted on the boys' birthday. "Happy birthday to these two sweet boys!! Our precious angels Mason and Reign. I love you more than words can say. 🎉🎉 #myheart" she wrote as the caption. Mason was born on Dec. 14, 2009, and Reign was born on the same day in 2014. 06 of 08 Growing Up on TV Kourtney Kardashian/Instagram Talk about an unbreakable sibling bond. Mama Kardashian snuck this precious photo of Mason and Penelope passed out in matching pajamas. Ever since Kardashian posted this photo on Instagram in 2017, the comments have been flooded with heart-eye emojis and it's pretty obvious as to why. 07 of 08 Building His Bond with Mom Kourtney Kardashian/Instagram Throughout each season of Keeping Up with the Kardashians, fans have seen the mother-son relationship between Kardashian and Mason grow into a really special one. This moment, captured and posted by Kardashian, shows the goofy side of Mason, which will be shown on a larger stage now that the 9-year-old will start filming confessionals on his family's reality show. Mason will be the first Kardashian kid to give on-air interviews but the twist is that auntie Koko (a.k.a. Khloé) will be asking the questions. According to auntie Kiki (a.k.a. Kim), Mason's confessionals are "so funny & heart warming." 08 of 08 Getting Older - and More Embarrassed by His Famous Fam When you're 9, you love your mom but she can sometimes be... embarrassing. That's how Mason felt when Kardashian started dancing to Tyga's song "Taste" on a StairMaster as he sat nearby. Aunt Khloé, who was capturing the whole "annoying" situation on Instagram stories, yelled, "Mason, moms dance too!" while laughing as Mason eventually bolted from his spot and ran out of the room.
