I have this lingering suspicion that my mental health was caused by the fact that I was fed formula over being breastfed as an infant. It's not that my mom had a choice, she just couldn't produce milk enough to sustain me so I was formula fed. I know my older brother was breastfed and he turned out super smart, has a steady relationship, and lives on his own with his girlfriend.

I and my kid brother both were formula fed and have had several psychological and emotional issues. He is an alcoholic and who knows what else, and I have MI problems that have plagued me all my life. I also have severe abandonment issues.

Is there a link between mental health and breastfeeding?
