Perhaps the biggest joy since leaving the White House was the birth of his first grandchild, Mila. Bush's youngest daughter, Jenna Hager, gave birth to Mila days before the library opened. Bush said the moment "completely captured" him and former first lady Laura Bush.
"It's a joy to watch Jenna mother her. It's a joy to watch Laura be a great grandmother. And, you know, I was telling Laura the other day, I can't wait to be able to take Mila around the ranch and answer all her questions about the trees and the animals and the grasses," he said.
Bush noted that there's a huge difference between being a father and grandparent.
"It's like a practice session in basketball versus a full-court press," he laughed. "I mean, you can show up and love and then pass back."
