Dara, the more you describe your son, the more he sounds like he could be on the autism spectrum--these kids can and do rage with the bipolar kids, and are often confused with them. However, speech delays and finicky eating are more an Autism Spectrum Disorders (ASD) issue than bipolar. In fact, many bipolar kids start speaking VERY early. They also tend to crave carbohydrates. You can't rule out autism/Pervasive Developmental Disorder (PDD) as young as your child. It was ruled out with Lucas too, but he has it. He's too young to rule in or out anything, really, unless it is blatantly obvious. I would get him into school early interventions and not worry about the label right now. If he has speech problems, I'd make sure he gets speech. If he has trouble expressing himself completely, I'd try to get ABA. If he needs PT or Occupational Therapist (OT) I'd get it. Social skills? I'd get it. My son couldn't get his Pervasive Developmental Disorder (PDD)-not otherwise specified label until he was 11, but he was in Autism Spectrum Disorders (ASD) early interventions before he turned a year old. I can't tell you how good this was for him. At fourteen he is functioning at a high level, no longer raging, and is a happy teenager, albeit "quirky." He used to tantrum, rage, hit himself, bite himself, etc. thus he got a bipolar diagnosis, but he was just frustrated in a world he didn't understand. Once he got help, he became almost mellow! He is my sweetest child by far right now, BUT we were proactive from the beginning. He was adopted at age two, and was already in early interventions before that, diagnosed with "severe ADHD." Well, we knew it was more. He didn't speak on time, yet he learned all his numbers, letters, colors etc. He was a really strange kid. His tantrums were scary. Once he learned to talk clearly (age 4 1/2), his tantrums disappeared, but they don't disappear in all Autism Spectrum Disorders (ASD) kids. Some need medications, like Risperdal. 50% of all kids on the Spectrum are on medication. But I think you're smart not to rush into a diagnosis or medications. No matter what you're told right now, it is likely to change as your child gets older. I personally like NeuroPsychs the best for evaluating. Psychiatrists completely missed the Autism Spectrum Disorders (ASD) in my son, even though I asked about it a lot, and gave my kid medications up to the wazoo. The neuropsychologist took twelve hours of testing, pinpointed his deficits and problems, and nailed him right. Good luck and don't focus on bipolar yet. Lots of things can cause tantrumming.
