Pattaramon Chanbua and seven-month old Gammy have been at the centre of a surrogacy controversy after reports emerged that the Australian couple flew to Thailand and took the boy's healthy twin sister at birth, but rejected the disabled child.
The 21-year-old surrogate said she would raise Gammy, who has been in hospital with a lung infection and heart condition for the last few days a couple of hours drive southeast of Bangkok.
"I never thought of having an abortion, I never thought to abandon him. I love him as my own baby... He is my baby. I love him very much," she said.
"Gammy is getting better step-by-step," she said, adding the USD 215,000 donated so far by well-wishers across the globe would go towards his treatment and school fees.

"From all of these unlucky things I am glad that we are together. I love him very much, I will never abandon him," she said.
Australia's immigration minister today labelled Pattaramon a "saint" and "absolute hero" for taking on the disabled baby despite already having two young children of her own.
"It is terrible, just absolutely horrible and heartbreaking," Scott Morrison said of the case.
But I have got to tell you who is an absolute hero in all of this and that is the Thai mother. She is a saint," he said.
"Sure there are lots of Australians who are desperate to be parents, but that can never I think sanction what we have just seen here."
But Pattaramon says she agreed to carry another Thai donor's egg fertilised by the Australian man in exchange for around USD 14,900.
An agency, which she refuses to name for legal reasons, acted as the go-between with the Australians.
