Journalist Chris Kornelis wants to help men get ready for fatherhood (and Father’s Day) with his new book “Rock-ing Father-hood: The Dad-To-Be’s Guide to Staying Cool.” He’ll be at Eagle Harbor Book Company (157 Winslow Way East) at 7 p.m. Thursday, June 16 to share his secrets.

Kornelis, a Bremerton resident who grew up on Bainbridge Island, found out he was going to be a father while he was the music editor at Seattle Weekly. The job required him to interview musicians and so he began to work in questions about fatherhood and parenting. As he gathered perspective and became a parent for the first time, he embarked on writing a book of his observations.

He began writing “Rocking Fatherhood” when his wife was pregnant with their second child, and he’s still amazed by how many of the same mistakes he made the second time around, he said.

But in the book, organized as a week-to-week guide, the author succeeds in offering honest advice that is both thoughtful and humorous.

Kornelis covers familiar topics such as living arrangements, finances, nutrition and role models, while exploring areas relevant almost exclusively to fathers. Chris uses his enthusiasm for Filson bags as a way to discuss both the benefits of a second job and cool diaper bags for dads.

He also spends considerable time on the topic of breastfeeding, based on he and his wife’s first-hand experience — something he wrote about in the Atlantic several years ago with a take that was lauded by many and vilified by others. He explains why formula can be a healthy alternative to breastfeeding, and encourages couples to do what they think is best for the baby and the family.

Kornelis writes regularly for the Wall Street Journal and has contributed pieces on topics ranging from Jack Johnson’s business acumen to Bill Nye’s bathroom clock. He’s also written about music and parenting for the Village Voice, LA Weekly, and the Washington Times.
