I am naturally cynical. In the article linked by differentnameforthis above there was a quote from the surrogate:
"“I’m going to save the money for him,” Ms Pattaramon said.
“Actually, I just want the baby to have a house. It doesn’t have to be big. I only want him to live in a good house and be comfortable.”"
Not that she wants his medical issues to be dealt with, or that she wants him supported in whatever way he needs, or that she wants to be able to look after him but still have educational needs provided for her other kids (which I understood was why she underwent the surrogacy in the first place). No, the thing she wants for her son is a house.
In the same article the Australian parents had been found, admitted that they had a daughter born to a surrogate in Thailand and claim to know nothing about any sibling.
I cannot believe the story about the father coming to the hospital and ignoring the boy if he knew the boy was the twin. That scenario seems more believable to me if indeed he did not know that the boy was a twin, because why would he be interested in some other, as far as he knows random, baby in the same hospital? IMO, the story about the father ignoring the boy in the hospital actually lends support to the idea that the Australian parents knew nothing about him.
I can't help but feel that the couple in Australia are perhaps unfairly being treated as villains here, and as someone pointed out above, they can't win now. If they didn't know about the boy before, what are they to do? If they bring him back to Australia they have "snatched him from the only family he's ever known", but if they leave him where he is they have "separated him from his twin and abandoned him because he has DS". If I were them I would be in hiding too.
In the same article the surrogate is quoted as saying she was not mad at the couple and never hated them. If she is indeed thinking of suing now, then I would say that someone has been egging her on and filling her head with ideas. Not saying that she wouldn't have a case against them, in fact, I don't know enough about either the law or the specific facts in this case to decide either way, but it is an about-face for her to go from not being angry to suing, makes me wonder who's been talking to her.
