Early education is absolutely necessary for the very young... just not school.
For example, 85 percent of the brain structure is developed between birth and 3 years and the way it develops is critical to future success.
The biggest influence isn't the children's education, it is the education of the parents. Meaning, the willingness to speak, play, learn with their children. Too many these days hand over an ipad and think their job is done.
Our daughter is very talented with language considering her age but, it is the grandparents who can really take the reward for it as they spend their time (a few days a week) playing and speaking about so many areas. We of course do the same but I think they go to a new level of play. She loves it.
Of course, a children that age need interaction with their parents. Lots of it. That much is clear. But that's not what the word means in this context.
