In PEOPLE's exclusive sneak peek of the TLC show's Monday episode, Garrick discusses how he's adjusted his future plans with Roberta after she made a full recovery from COVID-19. "COVID has shown us that we definitely have no guarantee of what's going to happen tomorrow," Garrick, 37, says in a confessional. "Our plan was always to get married in Mexico after her visa got approved. But with COVID shutdowns, it's still going to take quite a while before, you know, her visa is approved." Garrick adds, "So me and Roberta decided together that with her being 33 and not getting any younger, we're going to go ahead and plan a trip to Mexico — with or without the visa — to try to have a baby." Garrick's wife, Dannielle Merrifield, asks him about whether he's trying to conceive. After he confirms his decision, Dannielle opens up in a confessional about how that makes her feel.
