five houses.

wrt the story k12 posted above, well that's all lovely atm, but...
Firstly I wonder how much she was paid to hand over the baby, 10 grand? 20? 30? presumably in the states the amounts are limitless so exactly what price can you put on a child?
Also, she currently has contact with the baby and the new family but what if that changes? Friendships change and evolve and there are no guarantees that this family will want to stay in touch for ever, what happens if they wish to cease contact and this woman then loses touch with her biological child? Or if this family (and those in the future) parent differently to her - no-one knows what kind of parent they are going to be until they actually become one, how can you watch your biological child be parented in a way which you would not approve of?
Also it is IMO a very romanticised view that the three year old understands and loves the fact that her mummy is helping someone else to have a child, that may well be the case while the child is still three, five, eight, young enough to believe in fairy tales and happy ever after, but what about when that child is older and her mother has sold another ten of her siblings to unfortunate couples and she has siblings all over the country that she does not have a relationship with because her mother decided to give them away? I know someone whose mother gave up a baby for adoption because she did not feel she could cope with another baby (pregnancy was unplanned) and she felt the baby would have a better life elsewhere. The damage to her older children now that they are adults is immeasurable, especially the older one who has had to have therapy to come to terms with the loss of his sister.
It can be argued that biology is unimportant but of course it is. Why else do adopted children try to trace their biological parents, seek out relationships with their siblings etc if biology is not important?
If a woman wants to hire out her uterus and carry someone else's biological child for them that's one thing, but to do it with her own child, to give away, no sell actually since money changes hands, her existing child's siblings is totally wrong.
