how do you manage your kids mother tongue fluency?

[monstafish]

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.

im malay and i also noticed most young malay people and children cannot really speak their mother tongue too. but i think its important to continue your own culture, regardless of your race, so im quite happy that my childrens grandparents still communicate in malay with them.
