On March 5, the parents-to-be — who met and got engaged on Bachelor in Paradise — showed off Jade’s growing bump (using a chalkboard drawing to look ahead) during an exclusive photo shoot.

Now at the 13-week mark, they’re beginning to plan for their baby’s arrival: “If the pregnancy is low-risk, I would love to have an at-home water birth,” reveals Jade, who once considered becoming a doula herself. “But Tanner’s a little concerned.”

There's more he's worried about! Tanner says, “I’ll do every other duty if it means no poopy diapers!” Surprisingly, Jade’s OK with that: “He works a lot, so I’ll gladly take on most of the responsibility. I’m naturally nurturing, and I just can’t wait to have our baby.”
