 The intervention is delivered by a family specialist who, with the permission of the mother, will attend routine well-child visits so as to collaborate with providers in the childs medical home and parent through the medical visit. As desired by the mother, home visits, other face-to-face contacts, telephone calls, and text messages will assist in addressing social determinants of health, improve the mothers knowledge of child development and parenting, and link families to community resources to address existing concrete support needs. The family specialist will receive support and training by a licensed clinical social worker and the Medical-Legal Partnership, Boston MLP Boston to identify legal and social needs that may affect a childs health and development and to take action either by helping family members advocate for themselves, or by referring them to an appropriate public health, legal, or social service agency or resources.
