In 1828, she married David Lee Child and moved to Boston. Following the success of "Hobomok", Child wrote several novels, poetry, and an instruction manual for mothers, "The Mothers Book"; but her most successful work was "The Frugal Housewife. Dedicated to those who are not ashamed of Economy". This book contained mostly recipes, but also contained this advice for young housewives, "If you are about to furnish a house, do not spend all your money... Begin humbly." First published in 1829, the book was expanded and went through 33 printings in 25 years. Child wrote that her book had been "written for the poor … those who can afford to be epicures will find the best of information in the "Seventy-five Receipts"" by Eliza Leslie. Child changed the title to "The American Frugal Housewife" in 1832 to end the confusion with the British author Susannah Carter's "The Frugal Housewife" first published in 1765, and then printed in America from 1772. Child wrote that Carter's book was not suited "to the wants of this country". To add further confusion, from 1832 to 1834 Child's version was printed in London and Glasgow. In 1831, Lydia Child and her husband began to identify themselves with the anti-slavery cause through the writings and personal influence of William Lloyd Garrison. Child was a women's rights activist, but did not believe significant progress for women could be made until after the abolition of slavery. She believed that white women and slaves were similar in that white men held both groups in subjugation and treated them as property, instead of individual human beings. As she worked towards equality for women, Child publicly said that she did not care for all-female communities. She believed that women would be able to achieve more by working alongside men. Child, along with many other female abolitionists, began campaigning for equal female membership and participation in the American Anti-Slavery Society, provoking a controversy that later split the movement. In 1833, she published her book "An Appeal in Favor of that Class of Americans Called Africans". It argued in favor of the immediate emancipation of the slaves without compensation to slaveholders. She is sometimes said to have been the first white woman to have written a book in support of this policy. She "surveyed slavery from a variety of angles—historical, political, economic, legal, and moral" to show that "emancipation was practicable and that Africans were intellectually equal to Europeans."
