But don't start too early either:

I would say schools in general are more about warehousing kids than learning, although some kids do end up learning things they wouldn't have otherwise (while others end up not being able to learn things they would have learned otherwise).
Related to this discussion, several secular intentional communities in the US have attempted communal child raising and as far as I am aware all stopped after finding it to be worse than having parents be primary caregivers. Twin Oaks is the one I remember by name if anyone wants to go looking for info; I know their experience has been written about in books, I don't know if there is anything online. I am sure there were at least two other such attempts but I can't remember the communities right now. It seems kids really need at least one and not too many primary caregivers.
Foster care in the few states I know about in the US has serious problems. The interests of governments are not usually aligned with the interests of humans.
Parents do learn from the experiences of other parents and people everywhere are always looking for ways to do that better, but there are enough things that just don't work well that being too organized about it is likely to be counterproductive.
