Although Riley is the one quintuplet with her own space, she recently hasn't seemed too fond of that. During an episode of OutDaughtered, Adam and Danielle consistently caught their troublesome sleeper sneaking into one of her sisters' rooms to sleep.

When confronted about why she was leaving her bedroom, Riley admitted that she had been dealing with some pretty serious nightmares and felt more comfortable next to her sisters. 

Riley's ramped-up worries about sleeping on her own are now presenting an interesting dynamic change for her parents. The couple is diligently trying to figure out how to mediate her issues without reawakening the ones that were taken care of by putting her in her own room in the first place.

Catch new episodes of OutDaughtered Tuesdays at 8 p.m. EST on TLC.
