Female Attendant at Tooting Bathing Lake

A female attendant was employed for the very limited hours when women were permitted to swim at the Bathing-Lake. Here she is seen holding Reginald Craddick, the son of a friend. She's wearing a uniform more suited to the nursery than the swimming-pool and has a whistle round her neck (dangling over the baby's foot) to help her keep order. Sadly, Reginald died in infancy of tuberculosis. The attendant's name is unknown. She lived in Moring Road, Tooting. Can anyone help identify her?
