"She'll be, I think, a little over a year old by the time the wedding happens ... so hopefully she'll be able to be the flower girl and be able to be walking by then and do all that cool stuff," he continued. "But she'll be a part of the wedding no matter what."

"Well, first we didn't want to [show her in photos], especially when she was so young. We wanted to kind of keep that stuff personal to us and so we kept some of the photos and stuff like that for a while," he explained. "And then it kind of got to a point where we had her all the time and we enjoyed being with her so much and we were tired of hiding her from everybody."
"So it wasn't that we were trying to show her to the world I guess in a sense, we were just tired of having to hide her everywhere we went. We wanted her to be a part of our lives because she is such a big part of it," he added. "... It [gave us] a little relief off our backs that we didn't have to hide her everywhere and we could show her to the world and let them enjoy her as much as we do every single day."
