New Sibling

A newborn sibling being introduced to the family causes some sort of problem with the other sibling. This problem is typically that the newborn takes all the attention from their sibling and makes the older feel ignored by their family and sometimes friends and neighbors. The older sibling dislikes the younger one for this and may beg their parents to Look At Them.

Plot Sample
Jojo's parents have a new kid — Ruby — who seems pretty cute at first, but then starts to slowly take the people Jojo cares about away from her. Jojo tries her best to compete for her parents' attention again, but Ruby keeps getting in her way. Later, Jojo thinks her parents don't love her anymore and gets depressed. Weeks pass after Jojo's parents ask her what the problem is. She shares that she feels they don't love her as they're spending all their time with Ruby. Jojo's parents reassure that they still love her and tell her that taking care of a newborn is a lot of work, so they can't spend as much time with her. Jojo understands and can now live her life again.
