The mother of two also admitted that Lachie does sort of feel like one of her own kids.
"I do [feel like he's one of my children], he's absolutely special to me, and I feel like that with all of Toni's children, but particularly Lachie feels as though he's part of me."
"And you know what, I feel good about that," Toni added. "I feel good that he has another special person that loves him like I love him."
However, Sophie explained that the process of being a surrogate wasn't easy and that after giving birth to Lachie via C-section it was "hard" balancing what her hormonal body was feeling verse what she knew logically in her mind.
"I definitely had nights where I'd get a bit teary and feel hollow … you do, you feel a bit empty and in some ways that something's wrong," she said. "So you rely on your brain and your mind to tell you that everything has happened as it should and it's a happy time."
With the help of hormone medication, Sophie said that it took her around 10 days to come right and feel more herself again after giving birth to Lachie.
And while Sophie says she doesn't regret being a surrogate for Toni and her husband Matt, she admits that it isn't something she would ever do again.
"Absolutely not," she said when asked if she could do a repeat. "Not at all, it was a one-off it was a beautiful experience, but we got the outcome …"
"You can't top Lachie can you!" Toni joked.
