Here is a good academic article about it:

As a mother myself, I really pride myself on being able to give my daughter outlets- she takes dance lessons, she has adults in her life (both BP and non-BP) who support her, and we have fun traditions that she looks forward to (story time, going to the Childrens Museum).
While there is a genetic likelihood that she will get diagnosed with bipolar (which my ex never ceases to remind me that it would be my fault), I know enough about the illness where I would be able to support her.
Where I'm conflicted- I didn't get diagnosed until I was 30. I had my daughter prior to my diagnosis and was able to nurse for 9 months. I am so glad that I didn't expose her to the meds that I'm taking. Now I don't want to have a second child because of the medication, and the additional stress that a second child brings.
