The key thing with homeschooling is to find other homeschoolers so you and your kids aren’t isolated. There are local groups for homeschoolers. Find them. Try to recruit others with small kids to join too.
A key advantage of homeschooling is the opportunity for children to be part of the community. They can interact with people of different ages - adults and children.
Older children are perfectly capable of taking care of younger children, and can assist the adults. (Apparently this how one room schoolhouses were run - delegation of authority.)
Kids can be taken to see the real world in action.
Also having connections with other families can help with the time burdens. Also resources like text books can be shared, advice can be sought, etc.
Sudbury Valley schools are good. Definitely read how they do things - children follow their own pace. Even if they don’t choose to learn to read for a while that’s fine. When they they’ll be so in to it they’ll do well. (This is especially true of math - it isn’t hard but kids don’t like it so it take forever to learn.)
There are many great education articles on that site.
I also wonder about any program whereby the parent is too involved in the schooling. Part of it should be self discovery, the child working on things, etc.
If you want a curriculum for kids where they can teach themselves - see this
It is very science focused.
School is not necessarily bad if we believe in the division of labor.
Definitely google John Taylor Gatto if you start to doubt that schools are dangerous places to send kids.
With proper management both parents can be freed up to earn money. The older the kids get too the more independent they’ll be. The first 5 years most kids aren’t in school. The second 5 years kids go to school. But by the time they’re 10 kids are pretty much able to manage on their own for extended periods. They may look too small, but they’re actually quite capable. I remember at that age we were able to have discussions about the advantages of public and private school.
So basically you’re not necessarily adding that much to your workload by homeschooling. It all depends on how you do it. Private tutoring is great - but often the best way for kids to learn will be through reading and working things out on their own. Listening to a teacher lecture may or may not be effective. If they have questions your can help or help them figure out how to find answers. As you get older no one is there is answer your questions anyway - you have to do research and figure it out using your head.
