He's experiencing the intoxicating bubble of first time fatherhood.
And Aaron Paul couldn't be happier, writing movingly of his love for his month-old daughter Story.
Sharing a picture of the sleeping child snuggling in his wife Lauren's arms, the actor paid tribute to the women in his life on International Women's Day, reports Daily Mail.
Like many a loving parent, he was struck anew by the miracle of life.
"Life. To live," he wrote. "What an extraordinary gift that we as a whole constantly take for granted. It's easy to forget how lucky we are. These two ladies in this photograph are my world and they are a constant reminder how lucky I am to be alive.
"The little one on the right is my daughter and she just turned a month old. Her name is Story and each breath she takes makes me weak. The sounds she makes when she stretches and yawns are what I live for. Her sneezing and hiccups make me feel warmth like I have never felt."
Story is the first child for both Aaron and his wife, who he called a "damn good mother".
Said the Breaking Bad star: "The sleeping beauty on the left is my wife. Her name is Lauren and she just happens to be the greatest human that I have ever met and she just happens to be a damn good mother."
He met anti-bullying campaigner Lauren, 31, at the Coachella Festival in California, with the two then reconnecting at the three-day party the following year. They married in 2013.
Said Aaron: "Truth is, I never believed in soul mates before meeting her but I can tell you right now that she is mine. I guess that's how it works sometimes. Her and I somehow magically created this precious child and never has there been a greater gift for us. To be parents. What a blessing. What a miracle life is."
Welcoming his daughter has obviously been an intense experience for the actor, who at 38 came relatively late to fatherhood. However it's clear he is making sure to treasure every moment.
"Someone once said the odds of existing are as if two million people each rolled a dice that is a trillion sided and they all ended up landing on the same number. Think about that. How rare each and every one of us are. How beautifully perfect/imperfect each and every one of us are. It's crazy to think that we all started out as a perfect little sperm that happened to fertilize a perfect little egg on a very specify moment in time. Everything had to be absolutely perfect for each and every one of us to exist. Lucky us."
Aaron's words were well received by his fans, who flooded his Instagram page with their congratulations, and own memories of the wonder of early parenthood.
Among those touched by his eloquent post was a heavily pregnant mother, who shared that her child was expected to die at birth.
Clearly moved, Aaron told the woman: "I am so sorry to hear about your beautiful baby boy. I'm so happy that I saw your comment so that I could at least say hello and let you know that you are loved.
"Hold that little baby in your arms and never let go. I send you and your wonderful family all of the love and strength that I can give."
