One of the stories floating around is they plan to upstage the Coronation by throwing a HUGE birthday party for Archie...it would get coverage, but wouldn't upstage the Coronation. Even if it's a birthday party or releasing photo of the kids, it won't upstage the big UK event. It won't take the public by surprise...we're all used to the Sussexes pulling a PR happening when the Royal Family is in the spotlight.
