DS6 had a neuropsychological assessment in Oct. 2013 with the 2e experts Drs. Brock and Fernette Eide. Among numerous other recommendations (including an OG tutor), they recommended a book we could use at home called Toe by Toe. Due to scheduling we decided to wait on the OG tutor. Without doing any other recommendations we weren't already doing (reading with our son and getting him audiobooks) and just doing the Toe by Toe book twenty minutes a day, he jumped several years in reading in six months.

I highly recommend that book. It is available on Amazon.
