The album is set for release on iTunes and Amazon.com March 13.
Lachey and his wife, Vanessa, had their first child, son Camden, last September.
"When I first learned that I was going to be a father, I was inspired to create a special tribute to my son," Lachey said in a statement. "Music has always been an incredibly significant part of my life and a meaningful way in which I express myself. Creating this album allowed me to further connect with Camden while also sharing the experience with families who are on a similar journey of welcoming a new life into their world."
The album features 12 songs, four of which are original tracks Lachey co-wrote -- "Father's Lullaby," "Once Upon a Time," "Sleepy Eyes" and "Another Day is Done."
Additional hand-picked titles Lachey covers on the album include "All Through the Night," "Baby Mine," "You Are My Sunshine," "All the Pretty Little Horses," "When You Wish Upon A Star," "Godspeed [Sweet Dreams,]" "Hush, Little Baby" and "Brahms' Lullaby."
