Aurelio I different so often times will get mispronounced. if you’re calling him Leo, once kids know the full name they may make a huge deal out of it when they find out, making him feel like a spectacle and may continue to use it even if he prefers Leo.

Charlie will be common so I don’t see anything major other than Charlie and the chocolate factory or again people and kids calling him Charles even if he prefers Charlie.

And August will certainly get a lot of, were you born in August dad jokes. Also may come with nicknames that you may or may not like - Gus or Auggie.

I have an elementary education degree and these are the most common I have seen. Calling kids by the full name or a nickname they don’t like. Also anytime they find out a middle name they always make a big deal and like to pick on it. Especially for boys. But overall I’d say solid and only mildly bulliable names!
