When Helen Keller was a young child, before losing her sight and hearing, she was described as a healthy and normal baby. After her illness, she became a very difficult and unruly child. She experienced extreme frustration because she couldn't communicate her needs and desires, leading to tantrums and uncontrolled behavior. This behavior was a direct result of her inability to perceive the world through sight and sound, and her lack of a proper means to express herself.
