In a previous interview with The Father Hood, David opened up about becoming a dad "at a very young age."
"I think you mature quicker with kids. You have more important things in life to worry about than your everyday worries, and life becomes all about the kids," he said at the time. "I think that's what you learn as a father - you become less important and it's all about your children."
Also in the interview, David went on to share how his own father, Ted, inspires him in his parenting.
"'Never give up, no matter what.' That was one of the things that my dad would always say to me. If I got a kick in a game, I'd look over to him and he'd be like, 'Get up! Get up! Don't show people that you're hurt!' There was a steeliness that he kind of instilled into me on that side," he said. "It actually made me stronger as a person."

"Sleep well sweet dreams," the note continued, alongside several drawing of hearts. "Love, Harper."
