Lily L. Loud is the youngest of Lincoln Loud's ten sisters in the Nickelodeon animated series The Loud House. At 15 months old (two years old as of Season 5), Lily is a very playful and cheery baby. Prior to getting potty-trained in Season 5, Lily also had a tendency to stink up her diapers. Despite having only just learned how to walk at the start of the show's run, Lily is quite aware of the world around her, especially the antics of her older siblings. She is always happy to be around her siblings, all of whom care deeply for her (even bossy Lori and bratty Lola).
