The University of Michigan has been a leader in perinatal and infant and early childhood mental health for many decades. The field of infant and early childhood mental health nationally and internationally was launched by the pioneering work of Selma Fraiberg, a social worker in the University of Michigan Department of Psychiatry in the 1970’s. UM Department of Psychiatry has been instrumental in establishing the field of Perinatal Psychiatry to address the needs of women from preconception through pregnancy and beyond. Cutting-edge work continues today through the innovative multidisciplinary Zero to Thrive initiative, led by Drs. Kate Rosenblum and Maria Muzik.
