The changes she is experiencing and the different obstacles she is being faced with are making her use her imagination to make some real sense of what is actually going on. "She typically persists in fruitless attempts to relate her truly out-of-the-world' adventures to her previous in-the-world' assumptions."" (Rackin, pg. 40) In a way, this makes Alice mature, in the sense that she is facing a problem and trying to somehow come up with a solution. .
Alice begins fanning herself with the fan the rabbit that had gotten her in this mess had dropped, and realizes that it is making her shrink. She is upset once again when she realizes that although she is now the size she had hoped for, she left the key to the door on the table and is now too short to reach it, rendering her helpless. She asks a mouse for help, and then soon aggravates him by talking about her affection for cats and dogs. Birds and other animals are also immersed in the pool of tears Alice created, and she leads them to the shore. The fact that she was as small as mice and birds makes Alice's imagination explore the life of animals and what it is like to be that size. "Not only is Alice's previous identity apparently meaningless in Wonderland; the very concept of permanent identity is invalid. A pack of cards can also be a group of living people, a child can quickly turn into a pig, a cat's grin can exist without a cat."" (Rackin, pg. 42) This makes Alice mature a little more, because she is experiencing the same thing that rodents are and is now has their prospective on life and is helping them. Also, when she led all of the animals to the shore, it shows that she has learned some important leadership qualities and is using them to help her fellow imaginary friends. .
In the last chapter of the book, Alice eventually grows back to her normal size, while sitting in the courtroom with all of the imaginary figures. She grows because it's the end of the story, and it's no longer an imaginary tale about a girl in wonderland.
