This arm is the comparison group, which will receive standard prenatal and pediatric care with social needs screening and intervention as provided by the health care team as usual care (no medical-financial partnership intervention).

This arm is the first experimental group and participants included in this arm will receive the Medical-Financial Partnership intervention beginning in prenatal care and continuing into the postnatal period.

This arm is the second experimental group and participants included in this arm will receive the Medical-Financial Partnership intervention beginning in the postnatal period.

The Medical-Financial Partnership (MFP) intervention will include (at minimum):

1. A relationship with a trained MFP intervention team member
2. Establishment of financial and social goals in the initial meeting, with connection to public anti-poverty programs, employment opportunities, and other income supports, among others, as tailored to participant goals
3. Establishment of an action plan to reach short, medium and long-term goals in core MFP domains
4. Co-designing with the participant to identify and refine goals and action steps longitudinally
5. A standard toolkit for access to financial services and public benefits

Measured via participant-reported electronic or paper survey via the Patient Reported Outcome Measurement Information System Short Form Global Scale 10 Item Scale (the PROMIS-10; raw scale range 10-50 then T-Scored, with lower values indicating worse outcomes), this continuous measure is calculated based on Likert scale responses to 10 participant-reported questions/prompts. A mental health subscale of four items assesses depression and anxiety symptom burden and can be T-scored in preparation for analyses.

Collected via participant reported standardized Ages & Stages Questionnaire Version 3 (ASQ-3; each domain scale score ranging from 0-60 with threshold cutoffs for delays varying by child age, with lower values indicating a higher likelihood of developmental delay) forms on electronic surveys (preferred source) and at every well child visit beyond age 6 months. The presence of child developmental risk in any of five developmental domains (communication/speech/language, personal-social skills, gross motor skills, fine motor skills, or problem solving) will be measured at well child visits on parent-completed ASQ forms as well as every 6 months via online surveys from child age 6 to 24 months and rates of positive screens for developmental delay will be compared.
