The rhetorical question in this poem is asking about the development of a child. It's apparent that kids ask millions of questions, which is the most effective way children know the world and a part of the world becomes their lives, by asking questions, things become clearer to them and their development improves. That is the tool employed by Whitman to show the speaker's development throughout the poem.
Children are known to be very inquisitive, they want to learn about the world they are in, they want to make sense of their environment and every existence, so the only way for them to achieve this is by asking existential questions.
The rhetorical questions found throughout "There Was a Child Went Forth," by Walt Whitman are put in place to symbolize and demonstrate the development of a young human being. As children, they ask a great number of questions, and they absorb any and all information that they can get. This is how children learn and become the people that they will one day grow up to be. A child's questions may lead to further inquiries, sometimes even using rhetorical questions that cannot be answered--or are not expected to be answered--simply because it gives them something else to wonder and learn about.
