When your son's interest in finding goldbug inevitably flags, what worked for my kiddo was theatrically sighing, "I wish goldbug was on this page. Oh well..." and then acting like I was going to turn the page before I could be corrected. Then you can escalate to "accidentally" covering goldbug up with your thumb and pretending not to know he's under there. It's basically DLC for your board book!
