I'm bipolar with mostly depression, so will my baby have that too?

There is risk: The risk is not 100%, but it is higher for your baby than if you did not have bipolar. There is also an increased risk for anxiety disorders and mood disorders in children whose parents have bipolar. Again this is not 100%.

Possible Risk: If you have bipolar disorder, your child has a higher risk of eventually having bipolar disorder compared to the general population. However, there is still a much greater likelihood that your child will not have bipolar disorder. It is something to be aware of, but not something to automatically expect.
