The relationship between the surrogated mother and the baby depends on the method that is used. Since traditional surrogacy uses an egg from the surrogate mother to make the embryo, there will be a genetic link between the baby and the surrogate mother. When gestational surrogacy is used, the baby will be related to the woman whose egg is used. If it is from the surrogate mother then the baby will be related to her, if the egg comes from the wife, then there will be no relationship between the baby and the surrogate mother.
