“It’s nice to be reunited with this little nose picker – she still loves her dada,” the proud papa, 36, captioned the image reading a storybook to his tot.
Mama Leah Jenner recently posted a photo of their growing girl.
“Tiny expressionism enthusiast,” she captioned the image of their toddler enjoying the museum.
Caitlyn Jenner – who welcomed Brandon with his ex-wife Linda Thompson – says his oldest child supported her transition from the very beginning.
“I started with my son Brandon, because he’s like our little family Gandhi,” Caitlyn told PEOPLE. “He just has this great outlook on life and a very open mind. I figured he would be the easiest, so I sat down with him and his wife Leah and told them my whole story.”
Caitlyn added: “At the end, good old Brandon goes, ‘You know, Dad, I’ve always been really proud to be your son … and proud of everything you’ve done in your life. But I’ve never been more proud of you than I am right now.’ I cried. It was a really nice thing to say, and that really set the tone for (telling the rest of the family) and I started moving forward.”
