Is there a sin on the one who performed the delivery and did not know it was a sin?

Question: A woman was in labor, and they could not find a midwife. They told a woman who was with them to attend to her, even though she did not know how to do so. She stepped forward, and the baby was delivered on its own. This woman took the baby and kept it warm, and this was in the winter. The delivery took place in the house. After a week, the doctor told them that the baby had a cold and died. This woman is asking: Is there anything on her? And what should she do?

Answer: If the facts are as stated in the question, then there is nothing on the midwife; because she did what she saw to be in the interest of keeping the baby warm, and the original state is that the conscience is clear.
