If your three-year-old has been diagnosed with significant speech and learning disabilities, I would be reluctant to recommend home schooling. It's going to be very important that he has an opportunity to interact with other children while he is working on his speech and language skills and that a well-trained professional monitor his progress. Once he begins his speech and language classes in the fall, keep the lines of communication open with his teachers and ask them how you can reinforce their work at home. You can play a critical role in your child's success. Remember that you can ask for a reevaluation to assess the progress your child's made when he is ready for kindergarten and make your decision then about what kinds of supports he will need. Good luck!
