How does depression affect an unborn baby?

if depression runs on either side of the family genes, they baby may have a chance at having it as well. if both parents have depression the chance is greater than if only one parent has it. if you are talking about yourself having depression and wondering the affects it could take on your unborn child...many say that stress due to things like depression can cause preterm labor and can make for a colicky baby. talk to your doctor though they can help explain this to you.
