The model mom, 42, posted a sweet tribute on Instagram Thursday in celebration of son Benjamin Rein's 13th birthday. Alongside a series of photos of her son, whom she shares with ex Tom Brady, Bündchen wrote a heartfelt message to the teenager.

"We have a new teenager in the house ! Happy birthday my sweet angel! I am so proud of the kind, loving and courageous young man that you are. Thank you for bringing so much joy into our lives. We love you so much! ❤️," she wrote in both English and Portuguese.

In her Instagram carousel, Bündchen shared a snap of her and Ben sitting on a beach together at sunset, as well as shots of Ben climbing a tree, kissing a horse's head, hugging his siblings and making a funny pose on a dock.

Bündchen and a few other fellow moms brought their kids to the theme park, where they enjoyed rides like the Tower of Terror. The supermodel first shared a photo of ten pairs of sneakers lined up against a wall ready for the day, writing, "Let's do this!"

She then snapped a picture of all the kids holding hands as they walked through the theme park together, before showing a picture of their "chilling" experience on the Tower of Terror.

On Monday, the mom of two honored Vivian with a sweet post on Instagram for her birthday. She included pictures of the two playing in the ocean together as well as a shot of Vivian sleeping with their cat and petting a horse.

"Happy 10th birthday girlie girl! Thank you for being a ray of sunshine in our lives and for always spreading so much love all around you. We love you so much!❤️❤️❤️," Bündchen wrote in both English and Portuguese.

A source close to Brady told PEOPLE last month that the former couple's two kids will have "full access to both [parents], whenever they want" as they adjust to their new family dynamic after the pair's decision to divorce.

"They can see whichever parent they want. They've got a schedule, but neither of them would prevent their kids from seeing the other parent," added the source. "That's not who either of them are."
