Maybe ask about the seasonal affect on your mood? There seems to be many people on the bipolar forums that have this.

Other than the above I've no idea For advice. I wasn't as aware as you are when my daughter was that age...so I just bumbled through it. We have a good relationship now and that's all that's really important, I wouldn't worry to much about the other mothers, just do you best for you're kids and they'll understand that you are doing the best you can.
