The stress that it will place on you and your family is a strong argument against homeschooling. Not only do you have to prepare lessons on every subject, but you also need to have researched each topic enough to feel comfortable answering questions your child may have. This is a huge amount of work, and even after this, there is still the question of how to present the lessons. If the child is struggling to understand then they could blame you, resulting in animosity and resentment between you and your child.
