This product was first developed to help adoptive mothers induce lactation by feeding their babies at the breast to trigger hormonal changes that enhance milk production. It can also be used for premature, weak or impaired babies. This adjustable flow-rate system can also be used to give supplements while keeping baby on the breast. The Supplemental nursing system is suited for long-term supplemental breast feedings, has an adjustable flow-rate system and color-coded tubes for different feed rates. The neck strap and sterile packaging allow for maximum convenience and immediate use out of the package. All parts that come into contact with breastmilk are BPA/DEHP Free. This product includes an SNS container, valve holder, cap and cover, attachment ring, three sizes of tubing, tape, neck strap, and instructions.
