I'm disappointed that a tiger mom isn't anything like a cougar.
I believe in balance, our kids can watch TV - but they have to do a chore first unless everyone and watching. They have no TV in the bedrooms. They can choose what subjects they like. Computer time is also limited, but they can have the phone as much as they like. If they want to eat rubbish food they buy it themselves from their pocket money, we provide good food (mostly).
I think we're lucky that the kids like education, with the eldest about to embark to college to study physics, chemistry, maths and further maths - when nagged by his mum to do something for fun he replied that the further maths was for fun.
If my wife was a tiger mom I'd divorce her.
