She was educated by private governesses until she was eighteen. Her study of languages, literature, science and history was broad and she was an eager student. Her artistic talents were recognized early. Although she was provided with private art lessons, Beatrix preferred to develop her own style, particularly favoring watercolor.
She became unofficially engaged to her editor Norman Warne in 1905 despite the disapproval of her parents, but he died suddenly a month later.
