I'm probably not who you were targeting with your question, but I'd like to respond anyway, being the child of a bipolar parent (and being bipolar myself).
My dad hadn't been diagnosed as bipolar when he married my mom and had my sister and me, but he knew that he had problems. He had tried to get help as a teenager, but his father was unresponsive to his pleas for help. After I was born, my dad finally "cracked up" and was in and out the hospital all the time. When he wasn't in the hospital, he still wasn't well, was often suicidal, and was draining my mom, needing her to be a mother to him as well as to my sister and me. For a while my mom thought that if she loved him enough, she could fix him. But she eventually realized that she couldn't and that the best thing she could do for us was to get us out of an environment where all of her attention was having to go to my dad and where she was always afraid we might come home to find him in the corner dead. So they separated when I was four.
My mom tried to make sure that we stayed in touch with our dad, but that we only saw him when he was doing well. Still, my sister and I saw a lot that made us grow up fast and that made me resent my dad for a while. I remember sitting in the car in the parking lot of Wal-Mart when i was eight and having my dad explain to me the difference between homicide and suicide and telling me that he was sometimes suicidal. And when I was just out of eighth grade, my sister and I spent a weekend with him when he was extremely manic, unbeknownst to any of us when my mom dropped us off. It was very scary seeing my dad in that light, not really knowing what was going on his head or what he was doing.
My dad was notoriously bad about sticking to his medicine regimen and every year or so would decide that he knew more about being bipolar than his doctors and therefore knew better what meds he needed and would adjust his dosages without consulting anyone. And every time he did this, he'd wind up in the hospital, never learning from his mistakes the year prior.
My advice to you, as a bipolar parent, then, is, most importantly, always take your meds as they are prescribed and don't even think about adjusting them without consulting your doctor. Stability is very important for your kids, so you need to be very aware of your moods and how you're doing overall. Listen to people, especially those close to you, when they tell you that you're acting differently or that your moods seem to be slipping or that anything is out of the ordinary for you. And talk to your doctor/psychiatrist/whoever very early on. Adjustments in treatment are a normal part of life. We all go through it. But it's a lot easier to normalize things if we start getting help as soon as we notice things slipping rather than waiting until things have spiralled out of control.
Secondly, be honest with your children about being bipolar, but be thoughtful about how much you reveal to them and at what age. And be careful that you don't unload your burden on them. They're children. They don't need to carry the weight of knowing the depths of depression and suicide.
Also, realize that bipolar is genetic. There is a good chance that one or both of your children will inherit it. My mom knew this, but she was convinced that if she provided a good enough environment for us, she could beat nature. It is still important to create a very nurturing and supportive environment for your kids and to develop close relationships with them. But always be aware that there is a good chance they will have problems with mental illness. Be open about this possibility and encourage them to talk to you if they start to experience any symptoms. And, of course, be attentive yourself. (But at the same time, don't push mental illness on them. They might not develop anything.) Also, don't discount their feelings because they're young or write them off as typical teen angst. My sister was diagnosed as depressive when she was a teenager and, at 25, still struggles with it. I was hospitalized just after I turned 12 and diagnosed as bipolar.
Lastly, don't give up hope. Yes, you will face a lot struggles--managing your own bipolar, holding together your family even when things are really rough for you, raising your children with the possibility of them developing bipolar, and probably a few feelings of guilt thrown in. But it's all ok. That's life. We all get through it. And hopefully we all see that we're all doing the best that we can and are able to come to forgive each other for our shortcomings.
I hope my experiences have been in some way helpful or insightful. If not, my sincerest apologies for rattling on and on...
