BEING A SORRoGATE MOTHER!?

Do you think you would be able to be a surrogate mother? Have all the joy of pregnancy, having a precious little human being grow inside you, love that person with all your heart and when they are born you give them away because you were having them for someone else? All the little things you miss, their first smile, the first steps, the first words... I wouldn't! That must be so hard! Has anyone here been a surrogate mother? I watched something about it and it got me thinking!
