The exact number of Mrs. Bowles' children is not provided in the passages, but a character named Nora from Ibsen's 'A Doll's House' mentions having three children.
The passage you provided doesn't specifically mention the exact number of children Mrs. Bowles has, so it is impossible to provide a definitive answer to that question. However, in a different literary source, specifically the play 'A Doll's House' by Henrik Ibsen, there is a character named Nora who mentions having three children during her conversation with Mrs. Linde. It is essential while attempting to answer questions related to literature or specific characters within a work to reference the correct texts and materials for accurate information. In this case, unless there is a direct quotation or an excerpt from a text mentioning Mrs. Bowles and her children, one would not be able to provide an accurate answer regarding the number of her offspring.
