Pattaya: Pattaramon Chanbua points to a photograph of Gammy's twin sister hanging on the wall of her cluttered house 150 kilometres south-east of Bangkok.
"I miss her so much. I think of her every day and want to be with her," says the
"I also want Gammy to meet his sister, even if only for a short time, "she says.
"They should be together."
Gammy, who has Down Syndrome, was near-death when his sister was taken more than 5000 kilometres away to a remote Western Australian town only weeks after their births in a public hospital in Bangkok on December 23, 2013.
He has never seen his twin.
Chanbua, who is known as Goy, last year wrote a letter to the twins' biological Australian father David Farnell, a
"I never got a reply," Chanbua said, adding she has had no contact with the Farnells since they left Thailand with the baby in early 2014.
Chanbua told Fairfax Media she initiated legal action in Australia in 2016 to try to have Pipah returned to live with her and Gammy in Thailand because "I kept thinking about her living with a sex offender."
She said she has now accepted a WA Family Court decision to grant custody of Pipah to the Farnells, who live in Bunbury, under strict conditions.
"But I have not given up trying to see my daughter," she said.
WA Chief Justice Stephen Thackray found that Pipah, who had been raised by the Farnells since birth, lived a happy and contented life and would be traumatised if removed from the only parents she had known.
Justice Thackray found the Farnells lied under oath about Wendy being the eggs donor for the twins when the pair actually used an anonymous egg donor, together with David's sperm.
But Western Australia's Director of Public Prosecutions later said the state did not consider in the public interest for the Farnells to be charged with perjury.
Chanbua said she now wants to make a new appeal to the Farnells.
Gammy has been granted Australian citizenship, on the basis that her biological father is Australian.
Arriving home to take care of Gammy after finishing a shift at a bakery, Chanbua said she can't help thinking how Pipah's birthday would be celebrated in a country she has never visited and knows little about.
Gammy cannot speak but he is an active and mostly healthy toddler who likes dancing to music and taking selfies with his mother's mobile telephone.
"The doctors think he will speak when he is seven or eight," Chanbua said.
"They don't seem too worried."
