Caitlyn Jenner Documentary: 'I Am Cait' New Video Promo Released, Appearance by Her Mother [Watch]

Caitlyn Jenner posted a new video promo of her upcoming documentary series "I Am Cait" via the show's Facebook page.

"Sometimes, it can take a lifetime, to start living. #IAmCait," she captioned the post while tagging herself and youngest daughter Kylie Jenner on Facebook.

The video started off with a group of trans people making a toast to Caitlyn Jenner. She had just made two weeks of being a woman.

Her mother Esther Jenner appeared on the show to speak about how the transformation affected her. "My first feeling was that I lost my son and then I thought 'you know what, I'm gaining,'" she said.

Caitlyn went to an event and talked to a group of young children. "Hang out with the people who love you and respect you," she encouraged them.

The new promo also shows Caitlyn interacting with her children. She hugs her youngest daughter in one scene, and in the next she's crying while wearing a bath robe. "I want them to be proud of their daddy," she tearfully reveals.

It seems like Kris Jenner and Cait have the same taste. The transgender reality TV star talked to Kim Kardashian at the end of the promo video while they're standing in a closet full of female clothing.

"I love this dress," Caitlyn reveals while Kim tells her "Mom has one like this."

Meanwhile, Caitlyn wrote a blog post on her website about her "responsibility" to the transgender community.

"Up until now, I have totally isolated myself from the transgender community so I have a lot of catching up to do," she writes. "I feel such a responsibility to this courageous group to try to get it right and tell all sides of the story. To me, that's always the biggest question: am I doing it right?"

The celebrity went on to talk about how much she has learned in the few weeks since making her transition and she hopes to discover more.
