Emma Thompson regards "giving birth without painkillers" as her biggest accomplishment in life, despite scooping two Oscars for her film work.
The actress, 49, went through in vitro fertilisation (IVF) treatment to have her only daughter Gaia, nine, with actor husband Greg Wise.
And she admits that she is more proud of going into labour without the need for drugs than she is about her career success.
She tells Britain's Easy Living magazine that her happiest moment was "just after giving birth without painkillers".
However, she confesses to harbouring an unfulfilled ambition - to expand her family.
When asked what her biggest regret was, she told the publication: "Not having been able to have more children."
Thompson turned to adoption in 2003 when she informally took in then 16-year-old Rwandan refugee Tindyebwa Agaba, who she refers to as "my son".
