How to brush up on Chinese for the kids? We hardly speak it so it's worrying tht they don't get the exposure.

Can get a private tutor or find those tuition centre with small group like less then 8 people, they can learn faster. If you stay near Toa Payoh can look for this Fangcao Yuan Education Centre 芳草园 next to CHIJ secondary school, the teacher very good her lesson always full and many students from other location tuition there.
