The McGhee Sextuplets Have A Playdate With Another Family Of Multiples (VIDEOS)

While Mia McGhee was pregnant with her sextuplets, she met another mother of multiples in the hospital named Lynn. In the above clip from "6 Little McGhees," the McGhees sextuplets go on a playdate with Lynn's quadruplets at an indoor gym. While the kids have fun, the parents swap stories.

So far, Mia hasn't been having any luck potty training her 2-and-a-half year olds. Lynn, on the other hand, says one of her daughters is already out of diapers. "She hasn't had any accidents for a couple weeks now," Lynn says.

What's her secret? "I'm kind of doing it one at a time," Lynn says. When she tried to potty train all four kids at once, she says it didn't work.

"Oh my God!" Mia lets out. During her first (failed) attempt, she had tried to potty train all six kids at once.

"It's important to me to be able to talk to someone who has multiples, because you have to be a parent of multiples to understand what we're going through," Mia says.

"Six Little McGhee's" airs Saturdays at 10 p.m. ET on OWN.
