“For the better part of 20 years, I was a solo practitioner,” he says. “Then I got David, and that changed my dynamic.

“When you have kids, everything anchors to their wants and needs, so you get less sleep and have to be more aware all the time. You have to be adaptable because they constantly keep changing. They’ll do something that blows your mind and then they’ll spit all their food out on the carpet.

“The first year with them was complicated,” he admits. “They were twins, and they were crying a lot. Thank God for David. He is so good at differentiating cries.”
