I am posting this knowing the danger it may be closed. There are many helpful posts on this website covering multilingualism for children, e.g. this one. However, I want to educate myself in-depth on the subject. Hence, my question:
"What sources or books are there out there to help a parent in teaching their native language to their kid?"
I have found many links on "multilingualism and parenting" on the web, such as this one. Unfortunately, most of the coverage in the suggested books is on the benefits of speaking multiple languages...
My intentions are not academic. I am already sold, I do not need convincing. I want to know "how", not "why". I need a practitioner's guide. What (paid or unpaid) sources have you found useful?
Any recommendations very welcome.
