Breast Pumping

SALT is a multi-centre, non-blinded, non-randomized prospective interventional pilot study teaching lactating parents of hospitalized preterm infants how to test their breastmilk sodium (Na) using point-of-care (POC) meters. A drop in Na is a sign of secretory activation in the breast that is associated with adequate short and long-term breast milk volumes in this vulnerable population. Primary Objective: Establish feasibility, acceptance, and time cost of parent-led parent milk Na testing in the first 14 days postpartum Secondary Objective: Further investigate relationships between pumping behaviours, lactation risk factors, daily milk Na and lactation outcomes Exploratory Objective: Explore how POC Na data may be used to modify pumping behaviour and milk volumes
