Nova looked at the batter mix and the pink and blue food coloring as her mother said, “And tomorrow the party is because we’re going to find out if it’s a little girl or a little boy. Would you want a little brother or a little sister?”
The little girl excitedly said, “A little sister,” as her dad,Tyler Baltierra, looked on and said, “Oh.”
“You want a little sister?” Catelynn asked her daughter as Nova said, “Yeah.”
Tyler, who has expressed a desire in past seasons to have a son, asked, “What if it’s a boy? Would you be happy with a little brother too?”
“Yeah,” Nova said, before adding, “It doesn’t go away?”
Catelynn and Tyler, 26, both shared a laugh as he replied, “No, it never goes away. It’s here and that’s it.”
Nova then began listing all the things she would do with a younger sibling, saying, “I can rock it, and feed it bubbles. I can be [a] big sister. He’s so cute.”

The couple announcedthey were expecting their third childtogether in an interview withUs Weeklyearlier this week.
The mother of two previously announced she was pregnant on a January episode ofTeen Mom OG.But just a few months later, the couple revealed she’d had a miscarriage.
Catelynn, who was diagnosed with post-traumatic stress disorder, went to rehab last November toseek treatment for suicidal thoughts, and then again in early January toovercome childhood trauma.
Catelynn has been open about her fears of another pregnancy because she experienced postpartum depression after the birth of Nova.
“I’ve definitely been thinking about it and that’s the one thing that’s holding me back, honestly,” shetold PEOPLE of her battle with PPD. “Especially because they say if you’ve had postpartum once, you have a higher chance of getting it with your next.”
“With Nova, I thought it was severe because I struggled with anxiety already and panic attacks and depression,” she said. “So that is definitely the thing that scares me the most. I want to have a big family and have a lot of kids, but it’s scary. It’s definitely scary.”
