"Mikayla and DJ were great kids," said Dariel Walker about his two children. "And with them not being here, I feel it's my responsibility to show how great they would have been."
It's been almost three months since Walker's two children, age 3 and 2, were found dead in Bay County where sheriff investigators say their mother shot and killed them both before turning the gun on herself.
Walker says his children's mother had not been diagnosed with a mental health issue, but because of her tragic actions, he can't help but think she'd been suffering.
"She loved her kids very much," said Walker.
For Mental Health Awareness month, Walker has started a social media campaign to help create conversation and awareness of mental health issues and instill positive self images for people of all ages.
It's the My Little Champions Challenge using #mylittlechampionschallenge where Walker hopes people will post videos of their positive affirmations to social media, much like Walker did with Mikayla and DJ.
"When you instill these things in your children, you're giving them a priceless advantage to be able to take over the world," said Walker.
7 Action News reached out to relatives of the children's mother, but they declined to comment.
You can check out the social media campaign on Facebook, Twitter, Instagram and YouTube.
