I began homeschooling my daughter when she reached second grade. She was vaccine injured with her kindergarten shots, and began having absence seizures immediately (they progressed into grand mals when she hit puberty). She was enrolled in private school at the time, so the teacher, being a good friend of mine, would keep a journal of seizure activity for me. By first grade, the journal became harder for the teachers, and we realized that homeschooling would be our best option to work with the challenges of the seizures.
I am going back quite a few years with this, as my daughter is now 21 and taking college courses, living full time with us in Costa Rica while we run our ministry ... all that to say that homeschooling her (and later on my son as well, just because homeschooling is awesome!), was the best decision that we made.
My biggest advice to anyone homeschooling a child suffering from seizure disorders is to be patient and flexible. Make sure they are getting the rest that they need, even if it's inconvenient to your schedule, and to let you know that their diet is cruicial!!!
After many, many hours, days, years of research, we realized that gluten, grain and dairy were all contributing to seizure activity. We changed her diet gradually, and saw great improvement with her memory, clarity of thought, energy and seizure activity with each change that we made .... she is now 95% seizure free!
Go slow with them if you need to, work around their abilities, gifts and talents, and don't be hard on yourself or on them - we are a testament to the endless possibilities and treating her at home with us was the best family move ever!!!! Blessings to you -
