Charlotte herself was a healthy child, and according to her biographer, Thea Holme, "The impression one gets from all the early recorded stories of Charlotte is of a happy recklessness, and a warm heart." As Charlotte grew, her parents continued to battle, and to use the young girl as a pawn in their conflict, with both parents appealing to the King and Queen to take their side. In August 1797, Caroline left Carlton House, establishing herself in a rented home near Blackheath and leaving her daughter behind—English law at the time considered the father's rights to minor children paramount. However, the Prince took no action to further restrict Caroline's access to her daughter. In December 1798, the Prince invited his estranged wife to spend the winter at Carlton House, which she refused to do. It was the last serious effort at reconciliation, and its failure meant there was little likelihood that George would have a legitimate son who would come between Charlotte and the British throne. Caroline visited her daughter at Carlton House, and sometimes Charlotte was driven out to Blackheath to visit her mother, but was never allowed to stay in her mother's house. During the summers, the Prince leased Shrewsbury Lodge at Blackheath for his daughter, which made visitation easier, and according to Alison Plowden, who wrote of George's relationship with his wife and daughter, Caroline probably saw as much of her daughter as she wanted to.
