Welcome to the board and thanks for joining HealingWell.
That must make for some lively mood swings around your house. I have no experience dealing with an ADD spouse. Sorry.
I do think that if you haven't already, you should probably restructure your lives to make them as routine, stress free, and sleep-reliable as possible because all those things go out the window with a newborn, and yet they're all the things that make bipolar and ADD worse. Make sure you're taking care of yourself and ask him to be sure to take care of himself (meds, doc appointments, eating right, etc.)
Hope this is helpful,
congrats on the new baby,
