THE IDEA

*Old enough to have a baby*

a young girl(you deside how young) we will call her ?

becomes pregnant

one day in the middle of the pregnancy she complains to her mother

wanting to know when she will have the baby

Her mother responds not until your old/mature/ready/spicefic age/other

Enough to have it.

this wether deliberate or not results in a "curse" causing

? to stay pregnant for (as long as your heart desires)

Other details to consider does the pregnancy pause so she stays as pregnant as she is

does the baby continue to grow.
