In my opinion a good mother or a good father cannot be defined by the sperm who "produced" the child or the womb who carried the baby out.

A really good parent (surrogate) means for me clearly "caretaker."

A good parent is for me defined as a person who gives all this to the child:
- Love
- Time
- Money

There are cases known where surrogate fathers or mothers give all this more to a child than the "really" parents.

A woman who gets pregnant and carries the baby to term for another woman.

Surrogate mother is the person who will carry the baby for someone else....

Surrogates from my understanding is the one who carries and gives birth to the baby. It's a process. Mainly used for those who are unable to get pregnant due to physical issues. Also another option for those who are homosexual. Basically in vitro fertilization except the eggs or whatever is implanted inside of another woman.
