In fact, Carole Jackson, who works at the Center for Surrogate Parenting, said the ideal surrogacy is a "family project," one that can last up to two or three years if pregnancy doesn't occur on the first or second try.
Jackson, a mother of two who has been married for 27 years, has given birth to three children as a surrogate. She can tell within a few minutes if the woman is only interested in money.
"People speak from the heart right away," she said. "Or if the first five questions are about money."
Jackson is still close to the couple who are raising the twin girls she carried in 1999. "They know what I have done, and they call me Aunt Carole. It has been great watching them grow up and learn how they were created."
Wippler, who now lives in Oxford, Ala., agrees.
"The money isn't enough," she said. "You have to get more out of it. There's nothing like seeing the couple with the baby for the first time, knowing you made a commitment and seeing the end result. I wouldn't take four times the amount of money to be anonymous."
