Media personality Toni Street says she is still amazed her good friend carried a child for her, as she talked about her baby son in next month's Woman's Day magazine.
Street was denied the chance at having a third pregnancy after doctors said her auto-immune condition Churg-Strauss syndrome would make it too risky.
However, childhood friend Sophie Braggins stepped in and offered to carry Street and husband Matt France's third child, Lachlan Stephen France, by surrogacy.
"I'm still amazed that someone would do this for me," Street told Woman's Day.
"I was turning myself inside out over how I could ever thank her enough, but I'm learning to accept that she's done this because she loves me."
