Who does mrs. putnam think killed her babies? tituba ruth abigail a witch

In The Crucible (1953) by Arthur Miller, Mrs. Putnam thinks a witch, Goody Osburn, is responsible for the death of her babies.

Ann Putnam, Thomas Putnam's wife, thinks a witch has killed her seven children. She accuses Goody Osburn after Tituba names her to get blame off of herself. Furthermore, she believes Goody Osburn is guilty because she was present at the time of her failed births. Mrs. Putnam is sad and angry about the death of her children and that is what drives her to put the blame on someone for it, even if that person is innocent.
