Has the age of Confirmation Catholics changed since Vatican I?

There's some movement to a "restored" order for the reception of the Sacraments of Initiation, but with some sort of assumption that it should be received as early as age seven. I was listening to the Catholic Man Show [episode on teenagers](https://open.spotify.com/episode/5fuDGFpVtJnyYO5V4xZT7k?si=9983967898bc43a3) one of the hosts said that he didn't know the answer to this question and didn't get back to answering it. I teach a Confirmation class to high schoolers, the kind of material we go cover would go way over the heads of seven year olds (it barely resonates with teenagers), so I don't wholly understand how the same sort of formation would be possible for younger kids and as far as I can tell there is absolutely no formal preparation for confirmands in the Latin Rite as it currently stands. When I watch a movie like, the Song of Bernadette or hear stories about St. Therese, where these saints received the sacraments of initiation as teenagers, I have to think that the old ways were best. However, the normal age for confirmation hasn't really changed has it - or was there a period when Confirmation was received at an earlier age?
