At age 7, Alana "Honey Boo Boo" Thompson is preparing to become a first-time aunt to her sister Anna (aka "Chickadee")'s daughter-to-be, and already has her mind made up about her own future motherhood.

"I want to have children when I grow up," Honey Boo Boo confirms in an exclusive preview from Wednesday's episode of Here Comes Honey Boo Boo, which picks up after pregnant Anna, 17, takes a trip to a Georgia hospital after experiencing abdominal pain. "I want to have thousands and thousands!"

Though she's anxious to become a mother one day, Honey Boo Boo isn't convinced that caring for her niece Kaitlyn -- whom Anna welcomed in July after filming wrapped -- will be smooth sailing. "I'm not ready for Kaitlyn to come out. She's going to smell like poop!" predicts the former Toddlers & Tiaras star.

Watch more of Honey Boo Boo's musings on her extended family in the clip above before Here Comes Honey Boo Boo airs Wednesday at 10 p.m. (EST) on TLC.
