In 1887, she was sent to a boarding school run by nuns, preparing girls to the Brevet élémentaire ((French), approximately equivalent to the present British "GCSE" (General Certificate of Secondary Education) / Scottish "Standard Grade"), while giving them a substantial catholic education.

She was appointed Under-Secretary of State for Child Protection in Léon Blum's first government, reporting to Henri Sellier; Alice Jouenne served as Lacore's chef de Cabinet.

Afterwards, Suzanne continued to publish booklets, to write newspaper articles and to make speeches.

In particular, she stressed the benefits of nursery schools, demonstrating why it was important for a child to be educated from an early age.

Her efforts at improving the condition of juvenile offenders laid the foundations for the abolition, in 1945, of the maisons de correction ((French) literally "correction houses"), tough juvenile institutions where children were treated cruelly.
