Heather Rae El Moussa Marks Son's 3 Weeks Milestone With Emotional Video

Heather Rae El Moussa is delighted with her son, Tristan, marking a new milestone.

Since the birth of her child in January, the TV personality has always been one proud mother, so it was a no-brainer for the new mom to plan something special every time he clocks a huge milestone.

On social media, the "Selling Sunset" put up a pleasing video of her son while accompanying the clip with a short write-up. The video, set to a low-tone song, showed the behind-the-scenes of an adorable family photo shoot she participated in with her son and husband, Tarek El Moussa. 

In precise fashion, the "Love in the Time of Monsters" actress celebrated her newborn turning three weeks old with a family photography experience that she shared on her Instagram for her millions of followers to adore. 

In Heather's clip, fans see the realtor switch through several different ensembles as she first wore a long-sleeve black shirt and a pair of grey pants and eventually slipped on a lengthy blue dress to pose alongside her husband and their bouncing baby boy.

Heather's beautiful blonde hair remained tied into a pair of braids. On the other hand, Tarek cut a casual figure in a dusty blue t-shirt, denim pants, and white sneakers during the photoshoot. 

The Netflix star, who was on cloud nine, wrote a note in her post's caption that read, "Guess who's 3 weeks today ? Long but adorable video of our little love that I never want to forget. I've watched it over and over ?." 

Fans surged underneath the post to display excitement over the update, with many doting on the little one and his mama. Her mother-in-law, Dominique El Moussa, led the pack noting:

"My new little prince. We are all so excited for him to join in all our family adventures. Heather, you are a wonderful, caring, nurturing mom. ❤️❤️❤️.”

One follower wrote, "Heather. .your smile, looking at your first child is absolutely beautiful.I can feel your heartfelt happiness!! My Congratulations on your best blessing ever..enjoy every moment of this precious child ❤️." 

A second fan wrote, "He is absolutely beautiful," a third fan commented, "Omg you look sooo happy!! This is amazing. Bless your family ?. "You are such a beautiful soul and such a good mommy ???," a fourth commentator wrote.

Scenes from the emotional video bring to mind a recent report by The Blast where the real estate agent shared a solo shot of her young one and expressed how he has forever stolen her heart. 

Tristan was peacefully sleeping on a white sheet, rocking a white shirt with a "new to the El Moussa crew" print written on it. The round-neck shirt was paired with blue pants and a cap.

In the caption, the doting mother wrote, "New to the El Moussa crew ???. Mom's life is staring at him nonstop because I can't get enough ??." She went on, "The moment I held him in my arms he became my world."

The TV star also talked about sharing more information as a new mother by noting, "I'm thinking about sharing some things like my breastfeeding experience and how Tay and Bray have been with him so let me know if that's something you guys want to hear or if there's anything else."

The Blast recently reported on the couple's first appearance on a good night out. This particular night was a long time coming for the lovely couple who have been in the bliss of parenthood.

The 41-year-old shared their evening on Instagram. One clip showed the blonde bombshell walking in a black dress toward the door. Tarek, who was behind, said, "Alright, our first night out in what, how long? 11 months, 10 months, 9 months. I dunno, how long it takes to make a baby." As they walked along, the entrepreneur kept complimenting his wife's looks.

In another video, the mom of one was seated in the van, whose interior was decorated with balloons and petals for the outing. Over the post, he wrote, "@theheatherraeelmoussa You deserve the world ?❤️❤️."

Also, the "Flip or Flop" alum reposted a picture of them from his wife's account, where she tagged him alongside a white heart emoji. The image revealed his outfit for the night. He wore a blue unzipped jacket over a black shirt and jeans with white shoes.
