Though the Kardashian-Jenner clan has come around to accepting and spending time with Caitlyn Jenner following her transition, Scott Disick revealed in Sunday night’s episode of I Am Cait that he’s still trying to find the right way to broach the subject with his three kids.

Fifteen-month-old Reign is too young, but both Mason, 6, and Penelope, 3, remember Caitlyn prior to her transition.

“I feel like Caitlyn has been so busy running around and traveling and bringing awareness,” Scott explained on I Am Cait. “My kids don't really know exactly what's gone on. I don't know if they're old enough.”

Scott also revealed that both Mason and Penelope have spent time with Caitlyn, saying, “My daughter has met her and was totally ok -- didn't really grasp exactly that that was grandpa, now it's grandma. My son was a little nervous.”

Caitlyn’s friend Jenny Boylan advised the father of three to be open with his children, saying, “In my experience, it seems a bigger deal, I think, to grown-ups than it is to kids.”

Caitlyn went public with her decision to transition shortly after Kourtney Kardashian gave birth to Reign last year. Since then, Kourtney and Scott have split, but remain close, attending family events together.

In Sunday’s episode, Scott also got candid about the breakup, saying, “It’s been very tough. I’ve made a lot of decision that weren’t great.”
