The ideal family environment is different for everyone depending on cultural differences and social norms. An ideal family environment would include things like family dinners and game nights. Time everyday to spend away from electronic devices like computers and phones and have personal time to connect with each other. And it would incorporate a weekly night when the entire family comes together to have fun and play together.
Another aspect of the ideal family environment has to do with the parents. If there is constant arguing or corporal punishment like smacking or spanking, then it is not the ideal family relationship.
