They grow up so fast!

Just weeks ago, Terra Jolé and fiancé Joe Gnoffo were bringing home their little girl Penelope Charlevoix, and now the new parents are already bickering over taking their baby on her very first trip.

In a clip from the finale shared exclusively with PEOPLE, Gnoffo expresses his anxiety about taking Penelope on a plane to visit Jolé’s mom in San Antonio.

“You don’t need to go anywhere. You stay right here,” the proud father tells a sleeping Penelope as he plants a sweet kiss on her nose. “You’re too young to fly.”

Counters Jolé: “This is my mom and your mom has been able to see her. My mom hasn’t been able to see her.”
