@jnasevich Making a child theme can be very difficult if you don’t have the proper knowledge of it and can mess the whole the functioning and flow of the theme. I think this is the same in your case as well. I strongly suggest you to hire to developer to make the child theme or learn more about child themes yourself, try it on sample projects and then work on the main project.
As I said earlier: Copy all the content inside the attitude_headerdetails function of parent theme, paste it in the attitude_child_headerdetails. Then make you customization there, but when you are making the customization you need to completely understand the parent theme as well so you won’t break the theme and functioning.
