Australian parents contradict Thai surrogate mother's claims

The Australian parents and the Thai surrogate mother of a baby who has Down's syndrome have given conflicting accounts of how he was left behind.

Pattharamon Chanbua, 21, was paid by the couple to have their child but has said they took home only one baby when she had twins, leaving Gammy, who has Downs Syndrome, behind.

The parents of baby Gammy have told local media that they only knew about his healthy twin sister.
