Sorry for the late response but I have a question regarding this that I hope you can answer.

I'm also a long time anki user for the purpose of learning a foreign language. It is one of the core tools that got me to the level that I am today. I like it so much that I am also using it with my son. I'm using it for spellings mostly. But (and here comes the question) I'm also contemplating making him another deck for the foreign language that I'm studying, however, I'm wondering whether to have separate decks or just one big deck of cards. What do you do with your son? Different decks for different topics or just lump them all together in the same singular deck?

Any advice would be most welcome.

General advice here is that separate decks are easier to review, but a single deck will result in better retention thanks to benefits of interleaving.
