The Supplemental Nursing System (SNS) is a feeding tube device to provide babies long-term supplemental feedings at the breast. When a baby is at breast over a period of days or weeks, a hormonal mechanism is triggered that causes milk to be produced.

The SNS can also be used for:

• Inducing lactation
• Keeping special-needs babies at the breast
• Premature babies
• Weak, ineffective or lazy nursers
• Failure-to-thrive babies
• Impaired babies
• Low-milk supply mothers
• Relactating mothers
• A teaching tool to "fingerfed" babies who have had difficulty latching onto the breast
