At 15 months old, Lily is the youngest child of the Loud family. She is able to walk independently and is learning to speak. She has a tendency to poop in her diapers, leaving a foul stench known to disgust her older siblings and also often removes her diaper, forcing her siblings to put it back on.
Although just a baby, Lily is shown to be fairly aware of her surroundings, and especially of her siblings' many antics in which she is often swept up. Although still learning to talk, she seems to understand her brother and sisters quite often. She is very cheerful and loves to be near her siblings. She is most frequently seen in the care of Lincoln, Lori and Luna, who seem especially close to her.
