The former Olympian revealed he is transitioning to become a woman during an interview with U.S. newswoman Diane Sawyer which aired in America on Friday (24Apr15).

Kardashian has now opened up about undergoing family counselling sessions and receiving advice from activists at GLAAD, the Gay & Lesbian Alliance Against Defamation, to learn how to adjust to the changes and how to talk about Jenner's journey.

During an appearance on U.S. breakfast show Today on Monday (27Apr15), the reality TV star says, "I think there is still an adjustment and there's family therapy. We're really close... We all really support him. Is it a hard adjustment? Yes... It's an adjustment of how to deal with it and it's a daily process... We have been talking to people from the GLAAD organisation and different organisations on what do we call him? Do we say him or her? How do we be respectful?

"Until that transition is done, we've learned you do refer to him as 'him'. But Bruce has always been really, really good at explaining everything to us, even though this is really new and these have been newer feelings... Not newer feeling for him but for us to digest. He's done a really good job at walking us through it."

Jenner split from Kardashian's mother Kris in 2013 after more than 20 years of marriage.
