I think what it all comes down to, Fibi, is a trial and error period - finding out what your child needs and wants. I started my daughter off in home schooling because her father was very poorly and the little school where I had been teaching closed. Unfortunately, while that was the right decision for her, because we could not keep it up, it ended up being a problem. She was so far ahead of her peers that when she went to elementary school, the teacher didn't know what to do with her. That is why Montessori worked so well as I said earlier.
Every child is so different - you will find that with your own children when you are blessed with them. Everyone learns in a different way and, as Sarah said, the best thing you can do, pre-children, is to become familiar with the various schools you would have available when the time comes.
But it would be impossible to plan now for what your child-to-be may or will want in terms of education. And you will be amazed how much they will already know before they step foot in a school. Know what's available and then, when the time comes, try to match your child's skills and needs with what you can offer both inside and outside your home.
Parenting is an awesome responsibility - the decisions we make for our children are long-lasting if not permanent. When the time comes, you will have to figure it out, as we all have. Sometimes mistakes are made, sometimes we don't have all the information available. But to get as much information as you can is the key. Even then, it will still be a matter of whether or not "the shoe fits."
