The French mom is tough because her mom's life is hard. That's reality. But you may not know that it is a mess even before your baby was born ! Here in France, everybody puts pressure on you as a future mom right from the start, when you tell them you're pregnant.
So, all the French moms are not as perfect as they are presented in the books. However, the majority of us try our best to raise kids that would fit in our society. And the French society can be extremely cruel. I guess that's the reason why we are under pressure and that we do everything we could in order to have the most perfect kids ever (or at least, not to be ashamed by their attitude in public!).
