There are resources available for children, eg Muzzy is an animated immersion program for 5 year olds that (if you can bear the cheesy animation) might work. (In the US, available on Kanopy with a public library card.) And if you are good at searching you might also find resources that educators use for teaching recently immigrated children, although that implicitly requires a teacher/partner to be working with you.

Everyone learns languages in a different way. There are some people who like to be told what the basic rules of the language are and can use that to structure new sentences. Like giving someone K&R I suppose. Other people need to hear it. Personally, because I am only learning a language for practical purposes like travel, I'd love a course that dispensed with the grammar and taught contemporary phrases used in everyday life. For example, I am never going to ask and be told where the library is. But I'm very likely to hear, "cash or card?" or to ask "does this train go to Bologna?". So practicality for me wins early on, and then later I'd like to learn the top 500 words, and then the grammar structures.
