The baby continued to age and by the time the milk was gone, Katie's child was almost as old as Katie. She was maybe a year or two younger and she looked identical to a younger Katie, since after all she had only one parent. Except that her hair wasn't styled, and she didn't have makeup, or earrings, or even clothes. She was just... there.
"Mom?" said the girl.
"I can't believe this!" said Katie. "I just gave birth to you a little while ago, and you aged from drinking my milk... Can you, uh, talk? I mean of course you can, you just did. Do you know how to put on clothes?"
The girl thought. "I guess I do. But I don't have any."
"This is so strange!" said Tiff. "Katie, you have a daughter almost your age. I think you'd better name her."
"How about, er, Kathleen? What do you think?" she said to the naked girl.
"All right, Mom," she said. "I'm Kathleen now. We'd better get you some clothes...."
Surprisingly, they did find some clothes. Whoever had occupied the house before had left behind a lot of clothes of different sizes in the closet. Katie wondered why. For more experiments? Did whoever owned the house transform people into forms which needed all sorts of different clothes?
