At the end of about one month you looked something like a tiny curled up fish. You were still so small that your whole body could have rested on the nail of your mother's little finger; but you kept on growing.

Another month passed. You were now more than an inch tall and you began to look like a little baby.

After four months had passed, your mother felt you stirring in her body. She now knew that you were alive and that after a few more months you would be ready to be born.

While you were doing all this growing you needed food. At first you were fed in somewhat the same way that a chick is fed when it is growing in the shell. Your egg fed you. Only a small part of an egg, called the nucleus, grows. The rest is chiefly food for the growing part. The growing part soaks the food up into itself very much as a sponge or a washcloth soaks up water.
