Scott Moore has become the second transgender man to go public with the news that he is pregnant with his first baby.
Scott, 30, and his partner Thomas were both born female. They are legally married as Scott retained his female birth certificate.
They already have two children Gregg, 12, and Logan, 10, who they adopted after the boys' mother, Thomas' former partner, died.
"We know some people will criticise us,' says Scott, 'but we are blissfully happy and not ashamed."
In 2008 Thomas Beattie was the first transgender man to announce he was pregnant.
Like Scott, he had undergone chest reconstruction and testosterone therapy as part of his sex reassignment, but had kept his female organs.
Scott , born Jessica, knew he wanted to be a man since he hit puberty at 11 years old. His family were supportive of his decision and allowed him to start hormone treatment when he was just 16 and later, paid for him to have his breasts removed.
"I opted not to have a penis because I couldn't afford it and I didn't think the results were very good" said Scott, "it had nothing to do with wanting children because back then I didn't think I'd ever have them."
However, he and Thomas decided to start trying for a baby in 2008 and after being inseminated by sperm from a male friend, Scott fell pregnant in June.
Thomas, who used to be called Laura, started his gender transformation at the age of nineteen, eventually having a hysterectomy and penis construction surgery.
The couple's baby is due in February. It's a boy, and he'll be named Miles.
The family dismiss concerns that the little boy will be bullied because of the unusual domestic arrangement.
"We've been through it already," says Thomas. "My son Logan was bullied but now he just says to teasers: 'You may have a problem with my two dads but I don't so you're not hurting me'."
He added, "We want to show the world that trans-families can be healthy, loving and nurturing."
Is love and support all kids really need for a happy life, or do children need a traditional family structure?
