@torunn saidParenting is too important to be left to young people. Young people should be forbidden to make babies (let them have as much sex as they want, with contraceptives).
I would do many things differently but I was too young to know about parenthood. I would have applied rules and authority - Sweden during 60's and 70's was against all kinds of authority, both at home and at school, and we have never quite recovered from that. 🙂
Children need to learn limits. They must be taught to respect rules and authority, but without violence or physical punishment. Otherwise they grow up socio-paths, like Donald Trump.
