Kylie shared adorable images of her and her sister Kendall Jenner with their dad.
"So lucky to have you," she captioned the group of photos.
Caitlyn has been noticeably missing from the young mogul's Instagram feed.
Perhaps Kylie wants to avoid getting ignorant comments.
Bruce shared that his children did fear the reaction he would get before he began his transition.
"They all cried. Mainly because they didn’t want anybody to hurt dad," Bruce told ABC’s Diane Sawyer on "20/20" (he still occasionally referred to himself as Bruce in that interview). "They are very protective of me."
Kendall, on the other hand, did share an image of Caitlyn in her Father's Day Instagram Story posts.
"My dad is my dad, but he's not there physically anymore," Kendall told Women's Wear Daily in 2015. "But she lets me call her dad — that's the last little piece of dad I've got."
"Happy Father's Day to the soul that raised me," she wrote.
They all look so happy here!
At the end of the day how Caitlyn's family chooses to celebrate her publicly doesn't really mean anything.
What is most important is what truly goes on behind closed doors. We wish them the best.
