-- Father's Day is never easy for those who have lost their fathers.
"The Chew" co-host Daphne Oz announced on Instagram last February that her family was "heartbroken" after losing her father-in-law Sretko Dimitric to cancer.
Oz, 31, has been married to John Jovanovic since 2010. The couple has two children and recently announced they're expecting a third -- a baby girl -- next year.
The eldest child of Dr. Oz told ABC News that this Father's Day she and her husband plan to keep Dimitric's "memory alive for as much as we can."
It may feel like business as usual for her two children -- 3-year-old Philomena and 1-year-old Jovan -- since Oz hasn't broken the news that their grandfather passed away.
"We didn’t tell them because they feel too young to really talk about that so we talk about him all the time," Oz explained of her decision. "And that’s probably what we’ll do on Father’s Day too -- just remember him."
Oz, who is the face of the public awareness campaign TurnAfter2, which reminds parents to keep their children rear-facing in car seats until they're 2 years old, doesn't care if other parents don't understand her decision.
"The Happy Cook" author said she's dealt with many judgmental parents, especially on social media.
"I have gone through phases where I go through every comment [and it] warrants a response and then I’m like, 'My God, I don't need to justify to you how I choose to spend my time, or how much I love my kids; how much I love my family," she said.
She also recalled what her own father has taught her over the years.
"He’s endlessly curious," she gushed. "As his child, we were always very aware that he'd outwork everybody else. [He'd always say], 'Talent means nothing if you’re not willing to work hard.'"
