Statistically there's a 9% chance that your kid would get BP, 14% chance of major depressive disorder. Those probabilities go up with more evidence of MI in the immediate family.

I've never been interested in having kids, and it was an immediate point of agreement with my hubby. I had already decided that I didn't want to burden another soul with the kind of depression I had experienced already. My position on that has only strengthened as my mental health has deteriorated. I now know that I would almost certainly pass on ADHD and very likely MDD if not bipolar (80% of immediate family has/had ADHD, 100% of immediate family treated for MDD) so that basically just reinforces the choice. Notably, it's not just a matter of genes but also upbringing - that whole nature/nurture thing. For me, the nature half of the equation is already loaded in a way that would probably be hard to out-nurture.

We never wanted kids. I feel further justified in the choice because I wouldn't wish the kind of suffering I've experienced on my worst enemy, much less someone I love. For other people, the odds might not be so overwhelmingly negative, so it might be a harder choice - for me, it's easy. (Not to mention the part where I really don't want to have kids!)

A lot of other people around here do have healthy kids and are successful parents. So I'd say that same as all of them would - it's up to you and your husband.
