My grandson has Asperger's. He will be 5 next month and goes a day or two without speaking, but then will talk about his favorite topic, trucks, non-stop. He did not begin speaking till a little over one year ago, but did not do "baby talk". Just started right in like a 4 year old. He has ADDHD and is hard to control sometimes, but can be a real sweetie too. It is a challenge for his parents, but we are all learning to cope and to do what we can to maximize his enjoyment of life. He has been a computer "nerd" since age 18 months!! I am amazed at his ability there. Guess his brain and the computer think alike while mine is constantly distracted by life. So glad this disorder is being studied.
