Ashley Baldwin is testifying Thursday at the capital murder trial of abortion provider Kermit Gosnell.
The 72-year-old doctor is charged with killing seven newborns and a woman patient who died after an abortion.
Baldwin says she learned to do intravenous injections as a high school student and assisted with abortions.
Her mother, Tina, also worked at the inner-city clinic. She has pleaded guilty to corruption of a minor for letting Ashley work at what prosecutors call a corrupt organization.
Seven other employees have also pleaded guilty, some to third-degree murder. Another is on trial with Gosnell.
Gosnell's lawyer insists that no babies were born alive.
