March 27, 2012 -- When Sabine Bartlett was 13 her mother, who had been divorced from her father for a decade, transitioned from female to male.
Even though Sabine had grown up in a Unitarian Church with lots of gender and sexual diversity, Sabine knew little about being transgender.
Now 16 and living in Somerville, Mass., Sabine remembers her mother was "never particularly feminine," but began to "present as more butch."
"I came home from a trip with to my Dad's house and mom sat me down on the couch and told me she was going to transition," she said. "It's hard to face the fact that someone who is close to you changes at all -- especially a change that big."
A National Transgender Discrimination Survey of nearly 6,000 respondents revealed that about 38 percent were parents and at least 18 percent had at least one dependent child.
The 2011 survey was conducted by the National Center for Transgender Equality.
Transgender parents say that finding their true identity can be lifesaving for them, but at the same time, devastating for their children -- at least for a period of time.
"At first I felt a sense of loss, until a year later, when I saw that my mom was a much happier person," said Sabine. "Now, I am cool with this."
Just last week, New York City's Mel Wymore, a transgender man who is running for city council, discussed the difficulty his two children had during his transition from female to male in 2009.
"We have had very deep conversations and some negotiations around what makes them comfortable," he told the New York Times, adding the children are still allowed to call him, "Mom."
But Dana Beyer, a former surgeon who has run twice for Maryland state delegate, said, "Time heals all wounds if you allow it to."
Beyer hopes to be the nation's first elected transgender politician at the state level.
"I am trying as an advocate to normalize this as another medical condition," said Beyer, 60, who was born intersex [with a small penis and a partial uterus] and raised a boy. "No one knew what that meant then."
She had known since the age of 7 she was a girl, and like others who felt trapped in the wrong body, Beyer said she suffered from depression and even post-traumatic stress.
Beyer transitioned a decade ago when her sons were 14 and 17.
"The younger boy living at home at time no problem and this washed off his back," she said. "My older son was away at school and didn't observe the process and was little more uptight."
At graduation, her older son couldn't introduce his father, now a woman, to his friends.
The brothers wondered if his father's transgenderism meant they were gay. "It's an existential issue," said Beyer. "My father becomes my mother -- what does that mean for me?"
So she matter-of-factly asked them, "OK, guys, do you like boys or girls? … It turns out they were straight guys."
Now both boys are accepting of her new identity, calling her, "Dana."
"Secrecy is the most damaging thing," said Beyer. "You need to let them know you love them and it has nothing to do with them, but you can't hide it. Kids know if you are lying."
Other parents say that taking on a new identity came at a huge cost.
Sarah, not her real name, lost her job, a respectable life in the suburbs and her children when she transitioned from male to female.
"I lost pretty much everything," said the 50-year-old Boston waitress. "I had the American dream. A house with an in-ground pool, I was politically active and president of the Chamber of Commerce."
But the hardest was the loss of her children -- a 27-year-old daughter from a first marriage and a 17-year-old daughter and 16-year-old son from a second marriage.
"I never really understood my sexuality growing up," she said. "I didn't know what gay and transgender were. I thought, 'Oh my god, this is sick.' It was a major taboo in my generation."
Still, Sarah knew something was wrong. "I imagined being female, I was jealous of girls in dresses and I always kept it to myself. I lived in a male world and thought this is what I have to be."
As a man, his world revolved around his children. "I was very close to them. My marriage was on the rocks, but I wanted children -- I loved them so much."
Sarah eventually became depressed and attempted suicide. When the marriage fell apart, Sarah's wife served her with an order of protection and the court revoked her rights as a parent.
Sarah said the children were "scared and devastated" and aligned themselves with their mother.
Now, after facial feminization surgery in 2007 and sex reassignment surgery in 2009, Sarah said she has found inner happiness, but her heart still aches for her children.
"I will always be there for them when they want me," she said. "I just sit here and wait. It's all I can do. Everyone believes it was a very selfish act, maybe so in some way, but it was life or death for me."
For other transgender parents, one child was accepting and another sibling was not.
Teen Daughter Rebels Against Transgender Mother
Hunter Thompson, a 56-year-old divorced acupuncturist from Maryland, raised four children before he transitioned from female to male in 2006.
His oldest daughter, who was 27 at the time, was "fine" with the news. But his 17-year-old daughter "freaked out."
As a girl, Thompson always played with the boys and felt like a boy until puberty. "Everything went haywire for me," he said. By 18, Thompson contemplated suicide.
He married in college and had his first child before graduation. Two sons and another daughter followed.
"The only thing that made it OK to be female was I could produce male children," he said. "I always knew inside that I was male."
First he changed his name then he had hormone therapy. Now, he's had chest surgery and even changed his birth certificate.
"It was fantastic for me -- I started to be who I am," he said. But it was also a difficult time dealing with his children.
"My oldest was fine," said Thompson. "She was old enough to understand that I needed to be who I was."
He held off on telling his son, who was serving in Iraq. But his second daughter worried, "What will I tell my friends, what if I get married?"
She wondered, "What does this make me? Here I am female and my mother is telling me she is male. Does that make me some kind of freak?"
"She is fine now, but there were two years that were rough for her," said Thompson.
His youngest son still lives at home and the family gets together at holidays. The children now agree to call him "Hunter" in public.
"At home they call me Mom, that's fine," he said. "But it's got to be in private."
To other parents in transition, Thompson advises, "Be clear in who you are -- I really think that goes a long way. In the beginning I was terrified … But I was able to stand and say this is right for me and hopefully they will go down this road with me. Just be honest."
As for Sabine, even though she is homeschooled and lives in a liberal "bubble," she has faced the harsh judgment of her peers because of her mother's transgenderism.
"There was one girl I knew who told me if her parents did that, she would disown them," said Sabine. "I thought that was unacceptable."
"Friends can be weird about it," she said. "One friend I used to go to public school with asked me what it was like to have a transgender parent. That was a little strange."
Still most of her friends have been supportive.
Sabine said her sister, now 6, had an easier time because she was so young when her mother became a man.
"She says that there are some special men who weren't born men and some special women who weren't born women, and there are some other people who aren't boys or girls," said Sabine.
She admits transition is hard, but advises other children in the same situation to be patient.
"It usually gets easier after a while and, despite the changes, your parent will always be the same person," said Sabine. "Only, maybe a bit happier."
