In Charlotte's Web, we've got two different types of characters who grow up: kids and animals. And growing up isn't necessarily an easy feat. For an animal like Wilbur, growing up means gaining new friends and learning to stand on his own four feet. That's got to be a tough challenge. For a little girl like Fern, growing up means spending less time with Wilbur and more time with boys. That sounds like some tough stuff too. One thing is for sure: for all of our characters, growing up definitely has its ups and downs. But Charlotte's Web reminds us that everyone grows up, whether or not they want to.
You never really leave your childhood behind. Even if Fern grows up, she'll always be the same girl who saved Wilbur's life.
Eventually, everyone grows up and moves on. It's good that Fern grows out of her animal phase and starts acting her own age.
