Caitlyn Jenner's mother has called her daughter's public transition “courageous.”

Olympian Bruce Jenner came out as a transgender woman in April during a two-hour ABC News special with Diane Sawyer.

Caitlyn Jenner's debut on the cover of Vanity Fair made her the most high-profile transgender woman in America.

Esther Jenner, 88, told PEOPLE that she recently visited Jenner in Malibu.

“It was a wonderful day,” she said. “It takes so much courage to do what she's doing. When I first saw [Caitlyn], all I wanted to do was give her a big hug. It was such new information.”

“It takes some time getting used to. I've called [Caitlyn] Bruce since the day he was born. It's going to take some time. But I will adjust.”

“I love her,” the elder Jenner added. “And she's happy. That's all that matters.”
