YouTube star Myka Stauffer declared "my child is not returnable" before having her adopted son "rehomed".
Myka, 32, and her husband James have come under fire from their followers after confirming they had given up their autistic son Huxley, four, three years after adopting him from China.
They claimed that after bringing him home, they discovered he had "special needs we were not aware of".
However, in a YouTube video posted before the adoption, Myka explained they were warned of the severity of Huxley's condition by a US doctor who urged them not to proceed.
Myka insisted that "my child is not returnable" as they had started the adoption process and admits the doctor's guidance "went in one ear and out the other".
She also made it clear that the couple "would love" Huxley "no matter what state he came to us" in.
In the video, posted in January 2017, she explained that neurologists in China had given the youngster a CT scan and sent the results to her doctor in the US.
She said: "He had a neurologist and got a ct scan [in China] - we were 100 per cent prepared for that diagnosis. We were prepared for everything that it could be.
"When she [our doctor] got the imaging her optimism went down, it's nothing against this physician...
"Her prognosis was drastic - almost discouraged us from adopting him - she said this is going to be severe - it's going to be a lot, we don't know what these unknown elements could be.
"It was hard hearing someone say that... but I looked at the bright side. It could be awesome there could be so many good things about this second diagnosis.
"If anything my child is not returnable, so when I heard everything this doctor was telling us, it went in one ear and out the other. No matter what state he came to us, we would love him."
In another video posted before they took Huxley home, Myka admitted her husband James had doubts about the adoption after hearing a stark warning from doctors.
She explained: "I think he [James] had a hesitation when there was a time in his file when we got a call and they said 'Oh my God we don't know if you still want to adopt this child'
"They said he may be mentally retarded for the rest of his life and I really don't think you need to adopt this child.
"That's what the physician had told us. It was cool, we sat down and prayed I [said to James] 'If we brought him home and he was like that... What would you do?'
"And he said 'nothing' and I was like exactly! Nothing. Just like our other kids, you take them on vacation, you have fun with them, you tell them to stop painting on the walls.
James added that they saw many doctors and it was only one who gave them such bad news - and he hoped the prognosis was wrong.
He said: "That was the only worst case we got out of all the other nine referrals we had so that was reassuring.
"Everyone else said something different so it was like they could be right, they could be wrong we will find out."
