When kids go to school, they can have those conflicts with the teacher and you can just be the mom, which has its own set of conflicts. When you set yourself up to be the teacher, you invite both sets of conflicts into your relationship with your child. And your fear that he will want to go to school in the middle of the year just might come true. That's my opinion, formed from years of experience and discussions with hundreds of homeschoolers. I could be wrong though.
Every family is unique.
