Whether you totally embrace unschooling or just learn to relax more, I think you'll find that when you "Let go and let G-d" be in charge of what, and how, and how much, and how fast your children learn rather than on what the 'experts' in our culture tell us they need, your children will be happier, and will learn more -- not just for some stupid test then forget the information as time goes on, but truly learn and be interested in retaining and building on that information.

These 'experts' in institutionalized education and their curriculum and their standards and their expectations: who made them experts and if they are such experts why are so many kids functionally illiterate (a 20th century phenomenon, by the way), culturally illiterate, or just plain flunking out of school and life as well? And who makes money off of all this? The experts who teach and administrate in the schools and write and publish the curricula... Get the idea?
Who is the true expert -- the educational establishment or G-d?

This is something we come across so much, because it's so ingrained in our society. 'Our children should be learning thus and so because they're in the X grade.' Graded classes are part and parcel of institutionalization.

It bothered me for a long time what to do as an answer -- especially for my younger son who has severe dyslexia -- when my children didn't follow a graded curriculum.

As far as learning certain concepts at certain ages because the 'experts' say so (kicking the soapbox back under the desk in an attempt at self-control), which decade are we talking about?
Things have been so dumbed down over the years that we do a great disservice to our children by merely using a curriculum!

So here comes the question posed so often, and one that was asked of me by a curious acquaintance recently: "But won't there be gaps?"
My reply: "Sure -- but I went to school and have gaps in my learning too. Don't you?
......What's your point?"

I'm still filling in the gaps and will do so till the day I die!

Another question that comes up is in regard to children leading their learning and not having to do busywork.  It is asked, shouldn't children be made to do some things whether or not they enjoy or want to do it? After all, in adult life, we all have things that we don't want to do that we must do and the discipline for that must be learned.

To that I say that chores and other structure within a household and within our lives teach that discipline. Learning shouldn't.
Somehow we've gotten it into our head that learning is a thing to be endured, and we must do it, unpleasant or not.
What a sad world we live in that thinks that way!
