My 4 year old is currently undergoing a lengthy diagnosis through the school/child psychologist and doctors for Autism and one of the things they pointed out was his inconsistent learning. He does flash cards every night with me and has simple reading books. Sometimes we fly through the flash cards and other times he can't even give me the first letter. Have any of you experienced this or had a child with dyslexia. I've been told they are almost overlapping conditions in a minority of cases.
