There are various factors that can affect a child’s social and emotional development such as household financial stability, parental health, exposure to violence, and more. Supporting children who exhibit changes in mood or behavior is a priority for parents and early childhood professionals. Infant/Early Childhood Mental Health (I/ECMH) consultants play a critical role in this process by offering support and guidance to early childhood professionals, helping them to enhance and nurture the social and emotional development of children proactively, averting the need for intervention. Erikson Institute and its partners, the Illinois Early Childhood Asset Map (IECAM) at the University of Illinois Urbana-Champaign and Children’s Advocates for Change, carried out the Equity Analysis: Infant and Early Childhood Mental Health Consultation (I/ECMHC) Project, which aimed to:  1. Understand equitable access to I/ECMH consultation in Illinois by posing the question: How many consultants are serving in Illinois and is it sufficient? 2. Demonstrate the importance of I/ECMH consultation with data on the challenges children and families are facing in Illinois that can affect social-emotional development. (author abstract)
