Nikki Bella welcomed her first child, son Matteo Artemovich, with her fiancé, Dancing with the Stars pro Artem Chigvintsev on July 31.

The couple announced Matteo's arrival on Instagram on Aug. 2, captioning a photo of all of their hands, "Our baby boy is here and we couldn't be HAPPIER and more in LOVE! Everyone is safe and healthy." 

"The fact that he's here — I'm just so in love and happy," Nikki told PEOPLE exclusively. 

Brie Bella gave birth to son Buddy Dessert just 22 hours later on Aug. 1. She and her husband, wrestler Daniel Bryan, 39, also have a 3-year-old daughter, Birdie. 

The couple announced Buddy's arrival on Instagram, captioning a photo of the baby boy holding onto mom and dad's hands, "We are overwhelmed with joy and everyone is healthy!!!"

Birdie looks so happy to be spending time with her mom and new baby brother. 

"[Both babies] are calm and patient," Brie told PEOPLE. "We're the wild ones and very feisty. Our little boys don't have our personalities yet. Birdie does. Birdie is our mini."

"Hi I'm Buddy," Brie captioned her baby boy's first solo Instagram.

Nikki shared more details about Matteo, captioning his Instagram debut, "Matteo Artemovich Chigvintsev 💙 7/31/2020 💙 7 lbs 3 oz 💙 19 3/4 in."

In honor of Matteo's first month, Nikki posted a sweet snap of her baby boy. 

"Me and my boy 💙," Brie Bella captioned a series of selfies with her little Buddy. 

On her niece Alice's 2nd birthday, Brie Bella posted a sweet photo of the toddler with her baby cousin. 

The proud aunt and mom of two wrote alongside the sweet chat, "Can't believe she's not the youngest cousin anymore!!! Our sweet little Alice is 2 today!!!"

Artem got some "Dada time with [his] angel," snuggling him in a baby carrier. 

They do say that you should sleep when the baby sleeps! New dad Artem took advantage of the baby snuggles, captioning a sweet shot, "Dada needed nap 💤 time as much as Teo." 

Brie spend some quality cuddle time with her snuggle Buddy. 

Buddy spent some time with his big sister Birdie, which made their mom, Brie Bella, "sooo happy."

"This face officially owns me for the rest of my life," Nikki captioned a photo of Matteo with some adorable bed head. "lol My Teo can have it all from me! His hair here is giving me full emo vibes. 🖤🥰" 

"Sunday Laughs," Nikki captioned a photo of her beaming down at baby Matteo. 

Matteo doesn't look too convinced about sleep training, but his mom says he took to it faster than she expected.

"Before the Sunday laughs, Mama introduced Matteo to the first day of sleep training and I got the major Yo Ma Fuggedaboutit ... but once he realized it's not so bad he was all smiles," Nikki wrote. She added that she got her sleep training advice from her sister, Brie. Nikki gushed in a video of her son, "You've been doing so good, my love." 

The Total Bellas star wrote at the end of her post, tagging her fiancé, Matteo's dad, Artem: "he's SO your mini!! PS the sunlight shining right on my little man makes him look so blonde!" 

Cousins Buddy and Matteo had a cute date when they met up with their great-grandmother.

"Nana visits are the absolute best!!" Nikki said.

"The greatest feeling to see your Nana hold your baby!! 🥰," mama Brie captioned this heartwarming photo.

The DWTS pro raved about his fiancé and their baby boy. "My whole world," Chigvintsev said.

Brie shared a series of too-cute photos featuring her mother Kathy cradling Matteo and Buddy, who were dressed in custom Eagles jerseys while watching the big game.

Whether it's in the 2020 Presidential Election or for his dad on Dancing with the Stars, Matteo knows that your voice matters! 

Matteo smiled while his mom Nikki encouraged him during tummy time! 

Proud dad Artem captioned the sweet video, "Nicole and I absolutely obsessed with little Matteo his smile melts my heart every time ❤️ so proud of @thenikkibella for being absolutely the best mama there can be and all I can ask for I love you so so much and our little family."

His mom Nikki captioned an adorable set of photos, "I know what he's thinking... of course mom had to get the biggest pumpkin at the patch for me."

She revealed that she has a little helper who makes taking photos a bit easier: her niece Birdie! Nikki wrote, "He didn't want his beanie so Bird started dancing for him and how he was watching her! Omg the cutest! She loves singing and dancing for her Teo!"

Matteo and Nikki are the "Selfie King & Queen," with dad Artem commenting on the photo, "Nicole we have a model baby that magnum look is everything." 

Big sister Birdie told her brother, who she calls "Bud Bud" (we know, it's too cute) a "little story" as mom filmed and complimented her on being "such a good sister." 

"Someone wants to say Hi," the mom of two wrote along with an adorable photo of her son Buddy.

Little Matteo cozied up for a selfie with his mom and was dressed up in a jacket with cute ears on the hood.

Proud mom Brie shared two new photos of her son Buddy while playing with him at home.

"Our Teo's eyelashes!! I can't! 😩🥰 Baby boy is 19 weeks old already," the mom of one raved.

Nikki posted a shot taken by her husband Artem (@theartemc) with the caption, "My love @theartemc sent me this yesterday! My heart melted! 😭 Our Teo is growing up so fast!
