Following the births of George (1967) and Camilla (1970), Veronica suffered post-natal depression. Lucan became increasingly involved in her mental well-being, and in 1971 took her for treatment at a psychiatric clinic in Hampstead, where she refused to be admitted. Instead, she agreed to home visits from a psychiatrist and a course of anti-depressants. In July 1972 the family holidayed in Monte Carlo, but Veronica quickly returned to England, leaving Lucan with their two elder children. The combined pressures of maintaining their finances, the costs of Lucan's gambling addiction, and Veronica's weakened mental condition took their toll on the marriage; two weeks after a strained family Christmas in 1972, Lucan moved into a small property in Eaton Row.
