repeat the functions and senses of their bodies example, the eyes can see ,without eyes, I cannot see, without a nose, I cannot smell, this reminds the children of what each body part does, it also goes on to having a family meaning a mother and a father, how can they do anything without them, without their grandparents and so on. This is a great way for them to relate and understand not only their parents, but what their abilities are because of what they have. without you is an easy way for the children to remember in English, the different body parts and it's something they will want to read again and again.
