how do you manage your kids mother tongue fluency?

[Autumnn]

My kid isn't exactly fluent in his mother tongue but he's better than how he'd be if there's no YouTube.

My kid and us have a shared Google/YouTube account so my wife and I will add Chinese videos to the playlist for him to watch. Not just from the PRC but also TW, SG, MY. Basically, family and kid-friendly videos that he can enjoy and learn Chinese at the same time.

Some videos are even bilingual, which can make things easier especially if your kid isn't super fluent like mine.

having a shared youtube playlist is a nice idea! i think i will start one for my kids soon.
