Heather Rae El Moussa’s baby boy is reaching new stages.
The Selling Sunset alum shared a series of sweet pictures of her and Tarek El Moussa’s 2-year-old son Tristan ahead of his trial day at preschool.
“My mama heart,” Heather wrote in an Aug 5 Instagram post alongside pics Tristan flashing his dinosaur lunchbox and backpack for the camera. “My sweet boy had a ‘drop in’ at the sweetest little preschool today.”
“Even though we are not ready for pre school just yet..,” she added. “I am so proud of him and so happy that he loved it so much. And I’m proud of myself lol mama handled it well!”
Proving that she didn’t flip out over her baby boy’s milestone, Heather shared a video smiling for the camera as she held Tristan while he played with his lunchbox and she kissed him on the cheek.
Heather and Tristan’s latest moment came one week after she got candid about how it feels to spend time away from her baby boy.
“That moment when their little arms wrap around you and everything just feels right again,” Heather wrote July 29 alongside a video of her and Tarek reuniting with their toddler after a trip. “I think this was the longest I had been away from him and we were both really feeling it…little getaways are needed but I missed home.”
After all, Tristen is keeping Heather and Tarek—who also shares kids Taylor, 14, and Brayden, 9, with ex Christina Haack—plenty busy has he breezes past his milestones.
“He’s running around like crazy,” Heather told E! News last September. “He’s obsessed with bubbles, our dog, bathtime.”
Tarek couldn’t help but to join in and gush about their son adding, “He’s full of life, this kid. He’s so fun.”
