Although Chip and Joanna broke their tradition of choosing names that began with the letter D, there was one family tradition they kept alive and well. Letting her followers in on something that dates back to the birth of their first child, Joanna shared a sweet photo of her husband holding baby Crew on his lap with his wrist and the hospital bracelet clearly visible.
“Chip started a tradition with Drake where he wore the hospital bracelet until it fell off… looks like the tradition lives on. #5,” she said.
The Gaines hadn’t planned on having another baby before they learned they were pregnant with Crew, but they previously told PEOPLE that the idea of having kids around the house a bit longer is something they’re both excited about.
“We think about things like when Emmie goes off to college this little one will only be 10,” she said in April. “It’s just crazy to think how wide that gap is, but Chip just loves hanging out with the kids and it’s just such a sweet thing.”
