One day, the Teacher Doll was teaching a little girl, whose mother she had taught a long time ago, when she was little. She wished that she had a little girl of her own. The Teacher Doll had learned lots of stories and lots of songs, but none of the other children could hear her tell them. She was sure her own child would be able to hear them. Because she had always been kind, the Doll Fairy heard her wish, and saved it away for the right time.
When the girl got older she learned how to sew. One day, she was thinking about what to sew next, and an idea just popped into her head. She would sew a baby doll for one of her dolls. (She thought the idea got there all by itself, but we know the Doll Fairy helped it.)
But which doll? Not the Barbies, because they were always busy having adventures. Not one of the babies, because they were too young! Then she noticed the Teacher Doll, and thought that she would be perfect.
So the girl made the Teacher Doll a baby doll, with the same color face, and the same color hair, and the same color eyes, so it looked like her baby. The Teacher Doll's coveralls had a big front pocket, and her baby fit in just like a baby kangaroo.
Sure enough, her baby could hear her, and so she told her stories and sang her songs, and they lived happily ever after.
