Hi, OP. I was unschooled myself through the high school years. Instead of focusing on textbooks and lessons, my mom and dad moved my 2 sisters and I to the country and encouraged us to learn about things actively and according to our interests. We always had a very impressive stand at the homeschool coop end of year get togethers because other families would have school work and we would have real stuff, like stuff from our garden. Two of us, me included, wish we had had a more rigorous high school education because it caused problems in getting the high scores we needed on graduate exams and had problems with timed writing. On the other hand all of us have gone to college and gotten above a 3.5 GPA. One sister even went to graduate school, and I plan to in 2016.
Then I got married and had my son. He has had issues since he was born, first it was failure to thrive and then he had issues developing according to "schedule". He is very altert, active, and smart though. He just isn't very motivated academically. For a while people made me feel like I had to put him in school ( preschool even!) so he could develop normally and my confidence was shattered as a mother. Homeschooler generally teach like you said that children learn talking, eating, potty training and all that pretty naturally, but my son is not like that. It takes a very concerted effort to teach him things for him to learn. Last year after he started public school and we moved to a city area with a very substandard special needs program and a teacher who did not like him, we decided to pull him out and homeschool him ourselves. I found out through research that there are online public school charter schools that actually send you materials, have live classes and teachers, and he still has an IEP so we enrolled him in that. Funny thing is he is doing so much better now with us! Even with our faults we do a better job, with a little guidance, at helping his development than the educational establishment. He took forever in brick and mortar school just to learn to count to 5 and he knew hardly any letters, and very quickly after I pulled him out he was counting to 20. He now knows quite a few letters as well. His pottry training is taking off ( he hadn't been potty trained very well being in school half of the day). I do have the opinion now that unschooling would NOT be a good fit for him. He needs some academic structure so he will learn even if it is just directed by us in having him work on some workbook pages, or at the computer, or teaching him life skills. I think there needs to be a generally idea by the parents and goals for the day so young children can thrive.
Oh, I wanted to add that it is amazing how bad public schools are with special needs children. In his class they expected him to do workbooks most of the day! It is so ridiculous for a speial needs boy who is very active to sit still all day. He just can't do it. And then they wonder why there is an obesity epidemic when children are being taught not to move in public schools. Another issue, the biggest for me, is that the segregated the special needs kids in the school. Before school and at luch they have a special round table while the rest of the school has regular long rectangular tables, so regular kids would learn that they are the weird kids in the school and should be shunned. He also started feelng stupid, which really hurt my heart for him. We now have him say that he is not dumb and is smart in our school so he will have confidence in himself. Furthermore, my son had some behavior issues in the class even though he had already gone through 3 year of preschool pretty succesfully with a minor hicup here and there. H eas getting out of control in the class. This behavior problem even began to leak to other places. Funny thing is that almost immediately after we pulled him out his behavior went back to normal and he hasn't had many problems when out in public. Because of the behavior problem, in his parent teacher meeting they blamed us for the problem when it wasn't our fault that they couldn't control him in class. They wanted to do a behavior intervention on him and wouldn't let him go to art, music or recess, even special events. His teacher didn't even do anything to help him be pottry trained. He would always come home with a wet diaper and all the diapers I had put in his backpack still there. I am never going to put him back in public school, but I may decide to put him in a private special needs school or christian school in the future.
Sorry for the long post. This is a topic close to my heart. It is nice that someone else has gone through similar issues
