"It's never goodbye but see ya later #birthsisters #adoption," the mother wrote in the caption of a photo of Nova.
As fans may remember, Cate and Tyler welcomed their first daughter together back in 2009, Carly. The two were featured on the show 16 & Pregnant where fans watched the two place her for adoption.
Cate and Tyler both have discussed on Teen Mom OG how they have not seen their first daughter in a long time. Earlier this month Cate revealed on Twitter, "Sooo I get to see Carly this Aug!!! We are so excited and I cannot wait for nova to see her again!!! #blessed #Adoption."
Photos weren't shared of Carly from the exciting day and Tyler explained why! "I can talk about whatever I want. The rule is not to post PICTURES of her on social media," he wrote on Twitter.
Even without pictures, Tyler told his Twitter fans all about the amazing day. "Seeing Carly & Nova playing together, Carly pushing Nova in the stroller & holding her, omg you guys," he wrote.
In another tweet he wrote, "Carly ran right to me with a huge smile on her face when & I was holding Nova, it was pretty precious!"
