Steffy Forrester is someone who's worn many different hats during her tenure on "The Bold and the Beautiful." She's been a wife, a lover, a CEO, a friend, a daughter, and perhaps most importantly of all, a mother. Steffy had her first child, Kelly, with Liam Spencer, before he decided to waffle his way back to Hope Logan. She's always wanted to give Kelly a little sibling and had seriously considered adopting a child in order to complete her family (via Soaps in Depth). 

Soon after Liam married Hope, she became pregnant with their own child. But little did Hope know that the man who delivered her child, Dr. Reese Buckingham (Wayne Brady), was working against her. Dr. Buckingham delivered Hope's baby during a very stormy night at Catalina Island. But instead of giving the child to Hope and Liam, he sold the baby to Steffy, who adopted it without realizing where the child came from, nearly destroying Hope's life in the process.

The duplicitous doctor was trying to pay off his gambling debts at the time. He told Hope and Liam that their baby had died during childbirth, which left the couple absolutely devastated. It was an emotionally complicated time for everyone, as even Steffy felt guilty for having a beautiful baby while Hope and Liam were grieving the loss of their own (per Soap Dirt). At the same time, Steffy didn't know the truth until a certain someone came along and let the secret slip.
