Joanna Gaines on Juggling 5 Kids and Her Magnolia Empire: Crew 'Gave Me an Extra Kick in My Step'

"He's just like my second wind," new mom of five Joanna Gaines tells PEOPLE of son Crew

When Chip and Joanna Gaines welcomed their baby boy Crew in June, the Fixer Upper stars were already master multitaskers having juggled home renovations, a hit TV show, a burgeoning retail emporium and dozens of other projects, ranging from vacation rentals to magazines, memoirs and cookbooks, all while raising kids and running a 40-acre farm.

And rather than coping with typical postpartum exhaustion, the arrival of their fifth child — they’re also parents to Drake, 13, Ella, 12, Duke, 9, and Emmie, 8 — “gave me an extra kick in my step,” she says.

“It woke me up a little bit. Life was doing its thing, and this baby — typically you feel tired, but this baby, he’s just like my second wind.”

“I feel like it’s my life’s work,” she says of the detailed guide, which includes photos and examples from her own farmhouse, plus other homes she’s designed over the years.

“I love the way that I had to learn with trial and error. That’s why I really believe people can do this.”
