Lily Loud/Relationships

Her siblings generally
Since Lily is only a baby, her siblings tend to her every need and takes the best care of her. She is always happy to be around them and is able to tell when something is happening, like in "Cover Girls", she knew to cry at the right time to distract their parents before they noticed Lincoln missed his curfew.

Sometimes, things happens to her, or it appears that something has, due to their conflicts and antics, they would then put Lily first in solving the problems they caused, as shown in "Chore and Peace", when Lily going missing in the mess.

In "Changing the Baby", her siblings try to implement their interests on her because they had nobody that shares their likes.

Lincoln
She and Lincoln really love each other. Lincoln is one of the siblings who often carries Lily, changes her diapers, and burps her. He's very protective towards her as he is usually the quickest to save her if she is falling, for instance, he was the one searching for her the most when she went missing and saved her from Lisa's seemingly dangerous experiment. In "Changing the Baby", Lincoln spent his day with his sister Lily who was shown to enjoy doing so, though instead of becoming like Lincoln she instead chose to keep a hold of her blanket. In "Two Boys and a Baby" he babysat her and learned it isn't as easy as he thought. She and Lincoln are the two Loud kids who find clothes uncomfortable, so they relate best through this.

Mom and Dad
Her parents take excellent care of her, and make sure she doesn't get into any trouble. In "Chore and Peace", they take her with them to get her out of the garbage caused by the kids' strike. In "Two Boys and a Baby", it's revealed that her father is the one who usually looks after her while the rest of the family goes to visit Aunt Ruth.

Clyde
Clyde and Lily seem to get along pretty well at times. Just like Lincoln and his sisters, he can't resist the baby of the family.

In "Changing the Baby", Clyde fears that Lily will replace him as Lincoln's new best friend and tries to win Lincoln back by dressing up as a baby. When he realizes how cute Lily is, Clyde admits that he can't stay mad at her and decides to spend some time with her.

In "Two Boys and a Baby", Clyde helps Lincoln babysit Lily, thinking it would be an easy task, only to find out that it's much more difficult than intended. Lily at one point tears off strands of Clyde's hair, while she throws a tantrum.
