Speaking with Entertainment Tonight's Deidre Behar in 2021, the reality star said that she isn't interested in watching old episodes of 16 and Pregnant or Teen Mom OG — with one exception.

"When I am older and Carly is in her 20s or 30s, I'm blessed to be able to have a copy of my 16 and Pregnant episode that I can show her to ... I mean, right there is like, I don't even have to say too much," she said. "We can watch it. Then I can answer questions that she has because it was so 100 percent real."

"I still haven't been able to watch my 16 and Pregnant," she added. "I can't do it."

In a November episode of Teen Mom: Next Chapter, Lowell tells her husband about their daughter Novalee's emotional state when she got picked up from school earlier that day.

"She just started sobbing," Lowell explains to her husband. "She's like, 'I really miss Carly.' She's like, 'I don't — why did you have to separate us?'"

When the parents speak with their daughter about why she was so upset, she explains, "It feels like that's my sister and I can't see her that much."

Later, the couple reflected on the conversation, with Lowell explaining, "It just never occurred to me, when I was making the decision at 16, how it would impact my future children, you know?"

Baltierra felt the same, adding, "I guess I never really thought about it affecting them in a negative way."
