The most important caregiver in Liselotte's life was her aunt Sophia of the Palatinate, her father's youngest sister, who also lived in Heidelberg Castle with Charles I Louis until her marriage in 1658 with Ernest Augustus, Duke of Brunswick-Lüneburg. In order to deprive Charlotte of her daughter, in 1659 Liselotte was sent by her father to her aunt's court in Hanover; she later remembered this time as the happiest of her life. Sophia became in a motherly figure for her niece, and remained her most important confidante and correspondent throughout her life. During this time she also took a total of three trips to The Hague, where Liselotte could meet her paternal grandmother Elizabeth Stuart, the "Winter Queen" of Bohemia, who was still living in exile. Although in general she didn't particularly love children, she became very fond of her granddaughter, whom she found resembled to her own family, the Stuarts: "She is not like the House of Hesse...she is like ours". Her relatives in The Hague also included the slightly older William of Orange-Nassau, who was her playmate and was later to become King of England. She later also remembered the birth of Sophia's son George Louis, who also became King of England. As early as 1661, Liselotte knew French so well that she got a French woman named Madame Trelon, who did not understand German, as a governess. When Duke Ernest Augustus of Brunswick took office as Prince-Bishop of Osnabrück in September 1662, Liselotte moved with her foster parents to Iburg Castle.
