Tyler Baltierra is feeling the love. 

The 16 and Pregnant alum got candid about what it meant to spend time with his and wife Catelynn Lowell's four daughters—including 14-year-old Carly, who the couple placed for adoption in 2009 during the MTV show's first season.

"The feeling I have when I'm with all of my beautiful girls is truly indescribable," Tyler captioned a June 27 post featuring images of their visit with Carly. "The amount of pure organic love is overwhelming, almost to the point of being unbearable at times."

He added of Carly, "She's so smart. She's so kind. She's goofy & her laughing face is imprinting & infectious. Her parents have done such an amazing job raising her!"

The 31-year-old also spoke to how special it was to see all his children—he and Catelynn also share daughters Nova, 8, Vaeda, 4, and Rya, 18 months—spending time together. 

"It's pure magic watching her play with her sisters, because all you hear are echos of the same laugh & all you see are tons of hugs," he continued. "They have an unmistakable connection that's bonded between forces that are far greater than just shared dna…it's pure transcendental magic."

Tyler was also sure to give a heartfelt shoutout to Catelynn, his wife of eight years.

He said of the 31-year-old, "You are the BEST MOTHER I have ever seen & this family is only a family because of YOU! You are the most courageous, loving, wise & intuitive spirit & this family is beyond blessed to have you as its beautiful matriarch. I am so blessed to have you as my wife & the mother of our children…I love you more everyday!"

He finished his post with, "Until next time Carly, I'll love you forever!"

Catelynn also took a moment to reflect on the family's special day together.

"Had an amazing visit with our girl," she captioned her June 25 post. "She's funny, kind, SMART, goofy and STUNNING. Adoption is hard and saying goodbye time and time again is soooo hard!!!! But seeing all of our girls together, getting to know Carly deeper and deeper each time and being with all four of our daughters is truly such a blessing!!!!"

Over the years, the stars of Teen Mom: The Next Chapter have been open about their decision to document their experience with adoption on the 16 and Pregnant spinoff.

"I think it's awesome to be able to show the journey of an open, semi-open adoption through the years and the ups and the downs and learning and navigating this relationship," Catelynn told E! News in 2021. "I think it's super awesome that we can continue to do that in a way that can show our fans the journey but also in the way that it allows Carly's parents to feel comfortable with us sharing it as well."
