My twice exceptional son who had a 50% delay in motor skills at 12 months but was identifying letters before he was two and read his first easy reader book without being taught at 2 1/2 only a year after he started walking and could name words that were spelled out for him and could do Reader Rabbit First Grade at age 3. He was also very talkative and liked to use big words in his speech. He has not had an IQ test, only an individual achievement test. The educational psychologist guessed his IQ to be in the highly gifted range based on the information we gave him and the results of the achievement test.
