Well, I had made a couple of changes that took me forever to figure out how to do because I’m not familiar with modifying WordPress themes. I had tweaked the CSS to not show the edit button nor the date on sticky posts. I got that working and customized the banner to show the cupcake on her logo, and then my sister told me tonight that it had prompted her to update the theme. I don’t see any of the CSS changes I made, so I’m trying to remake them and will try putting them in the custom CSS screen so they don’t get overwritten by any future updates. I’m not even sure what you’re asking about a child theme, unless that’s where I changed the CSS and the header image.
