Brief Summary
The goal of this clinical trial is to learn about the impact of Kangaroo Care (holding your baby skin-to-skin on your chest) in lactating parents with babies in the Neonatal Intensive Care Unit (NICU) that cannot directly breastfeed.

Outcome Measures
Primary Outcomes (9)

10 days
Breast milk fat (g/dL) by kangaroo care intervention
The difference in expressed breast milk fat content between samples collected after participating in kangaroo care and those collected after having no contact with the infant for at least 6 hours.
10 days
Breast milk protein (g/dL) by kangaroo care intervention
The difference in expressed breast milk protein content between samples collected after participating in kangaroo care and those collected after having no contact with the infant for at least 6 hours.
10 days

Breast milk volume in mL by kangaroo care intervention
The difference in expressed breast milk volume expression between samples collected after participating in kangaroo care and after having no contact with the infant for at least 6 hours.

Study Arms (2)
Kangaroo Care Arm (KC)
ACTIVE COMPARATORLactating parents will be asked to arrive at the NICU 2 hours after they have fully expressed their breasts at home and to provide their infants with kangaroo care for 1 hour. Following KC and while still at the infant's bedside, lactating parents will be asked to pump from both of their breasts using a hospital grade pump available in the NICU. Study personnel will weigh the collected milk to determine the total volume of milk expressed by mass. The milk collected from both breasts will be gently swirled six times or more until the fat layer is incorporated in the bottle and will be combined into one bottle. Study personnel will take one 6 mL aliquot from the collected milk for compositional analysis. The remainder of the milk will be saved in the NICU per routine so that it can be fed to the infant later.
Control Arm (CON)
PLACEBO COMPARATORLactating parents will be asked to arrive at the NICU 3 hours after they have fully expressed their breasts at home. Lactating parents will be taken to a private room where they will be asked to pump from both of their breasts using a hospital grade pump available in the NICU. Study personnel will weigh the collected milk to determine the total volume of milk expressed by mass. The milk collected from both breasts will be gently swirled six times or more until the fat layer is incorporated in the bottle and will be combined into one bottle. Study personnel will take one 6 mL aliquot from the collected milk for compositional analysis. The remainder of the milk will be saved in the NICU per routine so that it can be fed to the infant later. Lactating parents will then provide their infants with kangaroo care for 1 hour.
Interventions
Lactating parents will participate in kangaroo care (holding an infant upright, directly on the chest with skin-to-skin contact) prior to expressing a breast milk sample.
Lactating parents will provide a breast milk sample after having no contact with their infant for at least 6 hours.

- Lactating parent is willing to use a hospital grade pump available in the NICU to express milk for sample collection
- Lactating Parent that is willing to travel to UCDMC on 4 occasions within a 10 day period for study visits
- Providers/staff:
- \. Physicians, nurses, fellows, residents, and NICU staff involved in the implementation of Kangaroo care for the MILK study.
You may not qualify if:

- Lactating parents that are unwilling to participate in kangaroo care
- Dyads that have participated in nutritive feeding at the breast
- Lactating parents that use recreational drugs that contraindicate breastfeeding/provision of breast milk
- Lactating parents taking therapies, supplements, or medications that are incompatible with breastfeeding/provision of breast milk to their infant
