'Teen Mom' Stars Catelynn Lowell And Tyler Baltierra Celebrate Many Milestones This Week

Catelynn Lowell and Tyler Baltierra have had a lot to celebrate lately. First an anniversary, then a birthday, and then the first day of school, all in a matter of less than two weeks' time.

While the two lovebirds have been together most of their lives, the "Teen Mom" couple just celebrated seven years of marriage on August 22. Lowell posted wedding snaps on Instagram with the caption, "7 years married to my best friend ❤️ here’s to a lifetime 🥂 @tylerbaltierramtv." Baltierra also posted an anniversary tribute on Instagram with a black and white wedding photo captioned with a poem and ending with, "Happy Anniversary babe @catelynnmtv I love you more than I could ever express! 😍❤️🥰"

As if that wasn't enough to celebrate, they also had a birthday to enjoy. Their youngest daughter, Rya Rose, turned one on August 28. Lowell, 30, posted a carousel of photos in honor of the occasion captioned, "Happy birthday to our last baby 😩❤️ Rya Rose 🌹 you are SUCH a good, smiley, loving baby! I can’t wait to continue to watch you grow and learn! Thank you for choosing me to be your mommy 🥰"

The post received more than 67,000 likes and 600 comments, with most comments wishing the adorable little girl a happy birthday.

And if an anniversary and a birthday weren't enough to keep the family busy, Baltierra and Lowell's 7-year-old daughter Novalee started second grade on Monday. Baltierra, 30, posted about her big day on his Instagram page. "Novalee’s first day as a 2nd grader! She picked out her outfit & everything. She was so pumped to go back to school. Seeing her excitement this morning & talking about it while I straightened her hair is a cherished memory I’ll make sure to keep forever! She’s growing up so fast…please slow down baby." He used hastags, #NovaleeReign, #BlessedByDaughters, and #GirlDad, on his post.

The couple are also parents to daughter Vaeda Luma, 3, and Carly, 13, who they placed for adoption while on MTV's "16 and Pregnant" in 2009.  Lowell found out she was expecting her first baby when she was a junior in high school. She told E! News last November, "I just remember the initial anxiety and being very scared. The scared is me thinking that I don't have anything. At that time, I didn't even have a cell phone. I didn't even have my driver's license yet. I didn't have a car," Lowell recalled. "My mom and Tyler's dad were kind of bad in addiction during that period of time also."

Lowell also explained that she feels that sharing her pregnancy and adoption journey on MTV could help others going through the same situation. "When our episode first aired on MTV in 2009, it was the very first episode that really documented what adoption looks like. I really do think that it opened the eyes for lots of people to really see how real adoption works and the struggles that birth parents go through and adoptive parents go through," she said. "It's not a Lifetime movie. It's authentic," she said.

Lowell was just 16 when she gave birth to Carly. Her and Baltierra agreed to an open adoption that allows in-person visits as the little girl grows up. "We text back and forth. We send pictures, I send pictures of my girls to them and they send pictures of Carly to us and updates on what they are doing and vice versa," she explained. All four of the couple's girls have been able to bond and spend time together.
