Hi A.,
OK, I haven't read most of the responses here yet, but I have some experience with pediatric bipolar disorder, as well as ADHD in children, and I wanted to post a response to you right away. I have also been a preschool teacher and liscenced daycare provider for more than half of my life, so I have cared for MANY young children with all types of personalities.
I am not convinced that your child has ANYTHING quite yet. I am sure that you and your child's father are most surely worried about the possibility of the genetic link to pass the bipolar "gene" to your son, so you are terrified about seeing any signs in him. (maybe??) That being said, I have a bipolar child. She was first diagnosed at age 4, and I refused to medicate her until just last year, at age 7. For a child it is most common to go through cycles of behavior that can run from days at a time, to months at a time. This is basically meaning that during these cycles their behavior would be either very Manic (up and happy) or very low or aggresive. (or just depressed or "bad" unruley) Now, during these cycles, the child can have moments when they are ok, and not behaving in an inappropriate manner, however, overall, the time frame is really a rough patch with several behavior issues and it seems lilke the calls from school or issues at home are never ending. Bad moods, getting into trouble, etc. My daughter was in a 3 month pattern for the most part. Now that she is medicated, she has stopped cycling all together. Prior to her being medicated, she was unable to make friends, was extremely bossy and controlling, and had issues sleeping. (In case you are wondering, this does run in her family, and she is not my biological child. I had to find out in a round about way, after the fact. It made the diagnoses MUCH harder, as well as much harder to accept) I fought the diagnoses for a long time because of her age, and now looking back wish I had not. I was so worried about the medication and the stigma. Her life is so much better now. However, she REALLY is bipolar. Her brother is ADHD, and also has issues sleeping. He is not medicated, but takes melatonin (which you can purchase in any vitamin section of the grocery store) to help him sleep. Ask the pediatrician about the propoer dose for your child if you want to try it. With ADHD the brain races and feels like it will not "shut down". Also, your child is 4 years old? MOst 4 year old little boys are very active and need a lot of excersize. Is he getting enough time to run and play? If he is very smart, which he sounds like he is, are you giving him enough to challenge his brain during the day? I would ask his teachers what they think. Do they see any issues with him? Have you been getting notes home from the school on a regular basis? I would not worry about something so serious because of a few rough days. All children have a few rough days. Did something change at his school? A new teacher or student? MOst kids will take the blame for any situation in their lives if you let them, and will think there is something "wrong with them" if they cannot do whatever is supposed to be done at school or at home. He may be feeling like his brain is "broken or screwed up" because he is having difficulty getting along with another child and can't figure out how to get them to play with him. You never know. Please don't stop watching him for signs since you do have the family history, but PLEASE don't label him too soon because this could very easily be a NORMAL childhood issue with regular solutions. I wish you the best, and God bless you and your husband! You are both on a long journey and I admire your courage and strength! Keep loving each other and that little boy! I am sure he will be just fine with loving parents as yourselves! :)
