One morning in 2013, dad Adrian Murray and his wife Michelle experienced every parent's nightmare. They woke up to find their 10-month-old son Emerson unresponsive in his crib.

The parents rushed their baby to the hospital, where he remained for three days. After severals rounds of tests, doctors still could not provide an answer as to what exactly was wrong with Emerson. A few days later, the Murrays brought their son back to the hospital after they found him unresponsive again. The baby was put on anti-seizure medication.

Emerson's ordeal was an eye-opening experience for his father Adrian, who was inspired to take photographs of his son's childhood. "I felt like life goes by in an instant and that I needed to try and capture those moments of wonder," he told The Huffington Post in an email.

Murray's photos of Emerson depict the little boy in moments of pure innocence and joy. Drawing inspiration from some of his own favorite childhood stories like Winnie the Pooh, Murray's photos "revolve around the idea of adventure and discovery," he explained.

"Our kids are bombarded by digital media, lights, and plastic. I wanted something closer to what child is all about, wonder and discovery," Murray added. "That's why we try to go to a park, or explore nature as often as we can."

Today, 2-year-old Emerson is in good health and no longer needs to take anti-seizure meds. This past February, the toddler became a big brother to "his partner in crime" Greyson.
