I just read it, and realised that we managed to get the best of both worlds.
Being older parents, in our mid and late 30s when they were born, we did not have the patience to indulge them, nor the energy to be up and down all night, so it was good manners at the table and in general, controlled bedtimes, early potty training, training in social manners, eg how to greet people and be introduced, proper food served at the table, always including vegetables, and zero tolerance of any behaviour that impacted on other adults.
However, we encouraged creativity and encouraged them to form opinions on whatever was happening in the world and in their lives. We gave them space to be bored, allowing only one outside of school activity each. For instance one chose soccer, another chose military cadets etc. They got the occasional smack, but usually 'That's enough' and a stern look did the job. Their Dad being ex-military helped, I think.
The French get most of it right, but their schools are too cold and indifferent. My Brother in law tried teaching in them and gave it away in favour of teaching English to adults. Perhaps the parents are a bit too hard too, but you have to admit, when kids are well behaved, society is more pleasant.
However, one thing that probably helps to keep French children civilised, is the food. It is rarely discussed, but junk food and poor eating habits impact on behaviour as well as health. The French eat well, and always at the table. They don't graze. They don't drink copious amounts of fizzy soft drinks. And their meals are usually healthy.
