Jared Padalecki
is opening up about the life-changing joys of fatherhood in a heartfelt letter he wrote to his three adorable children.

The Supernatural star's wife, actress Genevieve Padalecki, recently shared the touching message to her blog, where she explained that Padalecki had penned the missive to their kids -- 5-year-old son Thomas, 3-year-old son Austin, and 3-month-old daughter Odette -- soon after Father's Day.

"The kids may be a little too young to fully appreciate it, but one day I hope they read this and know what a great dad they have," she wrote as an introduction to the letter. "When it comes to being a father, Jared has found his calling."

The 34-year-old father
wrote that, after celebrating a holiday that honors fathers, he wanted to turn the tables and share some gratitude for the impact his kids have had on his life.

"I wanted to take this opportunity, after my FIFTH Father's Day (and counting), not to say 'you’re welcome,' but to say 'thank you,' he wrote, before listing the many things his kids have done to change his life since they were born.

Some of the examples include, "You’ve woken me up earlier than a rooster would even CONSIDER crowing," "you’ve given me sleepless nights where I thought you might NEVER, in fact, go back to sleep," and "you’ve coerced me into watching cartoons and animated movies over and over and over again… and over again."

While the list might seem to be filled with light-hearted complaints, the letter goes on to explain how his life has benefited from each of those unexpected experiences.

For waking him up early, Padelecki thanked his kids for "all of the extra sunrises I’ve been able to witness."

For all the sleepless nights, he thanked them for "letting me experience that special feeling you have when you know the world around you is sleeping."

And for making him watch cartoons, he wrote, "Thank you for giving me a believable excuse to watch Lion King and Ninja Turtles and Paw Patrol (i really do love them :)…)" And those are just a few of many super sweet thank yous the proud pop shared.

"Thank you for letting me feel what it's like to love something more than yourself," he continued. "You’ve taught me more than any mentor or teacher ever could… you’ve humbled me. You’ve helped me rediscover the joy of discovery. You’ve turned my world upside down. And I wouldn't have it any other way."
