It's true that no mother likes being advised on how to raise her kids. But it's also true that every mother can't help but advise.
In the same vein, here's my advice to Singaporean moms including myself - do not underestimate the importance of unstructured play! Avoid the urge to always plan activities for your kids or teach them how to play a game while on the playground - well not all the time. Surely there's value in your child getting bored & having to invent games for himself out of sheer boredom.
