The girl from Abbeymead, Gloucester - who cannot be named for legal reasons - gave birth in the bathroom of her home while her family was out shopping and cut the umbilical cord with a pair of scissors.
The girl told police the baby was dead when it was born. But Gloucester Coroner's Court was told it had probably lived for a short while after the birth.
The teenager's mother told the inquest she only realised her daughter had given birth when she found the baby in a drawer under her daughter's bed. She had put her daughter's weight gain down to her splitting up with her boyfriend.
She said: "She wishes she was dead and not the baby. She is very distraught. I know she will never get over this."
The coroner recorded an open verdict.Reuse content
