3. To evaluate the short-term impact of a maternal-driven intervention bundle on the mother-infant dyad. Maternal stress will be measured using the Parental Stress Scale for NICU patients (PSS: NICU) prior to the intervention and prior to the infant's NICU discharge. Further, stress will be assessed by measuring maternal and infant salivary cortisol pre-and post-kangaroo care on 3 separate occasions (post enrollment in the study, mid-hospital stay, and prior to discharge). Measures of maternal anxiety and depression will be evaluated prior to the intervention and prior to NICU discharge using the Patient Reported Outcomes Measurement Information System (PROMIS) instrument.
