Why would poor maternal mental health during pregnancy affect postpartum childhood development?

i understand why it would postpartum, because of the interpersonal interaction between mother and baby. but how does this have an impact during pregnancy? aren’t mothers and babies only connected physically, i.e. sharing a blood stream? or does this have something to do with hormonal imbalances or something similar?
