how do you manage your kids mother tongue fluency?

[jenzz]

hello fellow parents, I'm wondering how you make sure your kids are fluent in their mother tongue?

my husband and I try to mix in spoken Chinese when we communicate with our kids but it doesn't seem to have a great effect because:
1. our Chinese isn't that fluent in the first place
2. they watch mostly English media

so please share if you have any tips.

i tink some things are out of our control. for example, the friends that our kids mix with will have a big influence too. like if their friends speak chinese or their mother tongue too, then it will seem 'normal' to be good at mother tongue. if their friends think speaking in chinese or mother tongue is 'not cool', then our kids will be affected too.
