As a prime ministerial spouse from March 1971 to December 1972, McMahon organised for a nanny to look after the children at the family home in the Sydney suburb of
Bellevue Hill, while she lived with her husband at
The Lodge, Canberra, attending official duties. In an interview with her biographer, McMahon said: "It was a hard decision. I loved being with Bill and I loved being a mum. But I knew I had to make a decision, and I chose to be with my husband."
William McMahon was knighted in 1977 and as such she became Lady McMahon, although was often still referred to as simply Sonia McMahon.
