First, nobody TRULY understands your circumstances more than you do. As each new learning approach and curriculum comes along, you will have to analyze it and see if it works for you. Your love for your child and understanding their heart along with prayer will guide you to successfully navigate your way through this journey.
Too, homeschooling a special needs child takes courage but also there will be times that you will need to get away from them. In order to be refreshed and renew your energy, take time to do that. You need this more so than any other parent that is homeschooling. On a daily basis, you may be dealing with outright acting up to almost no input receive from your child.
