Kody says that he is distraught over his child's rite of passage. "Mairah leaving the nest kind of breaks my heart."
Meri has struggled for the last few years trying to decide if she wants to have another child with Kody so preparing for Mariah to leave the house and go away to college is incredibly difficult for her.
"The fact that she is my only child, and that I really will be an empty nester after she goes, is what makes it harder for me," she says.
She says that she still is holding onto her little girl.
"I'm not ready to let her go."
