OG Tube: Helping Your Baby Receive Nutrition Through a Feeding Tube
What Is an OG Tube?
An OG tube (orogastric tube) is a small, soft, flexible tube that passes through your baby's mouth and down into the stomach.
It allows your baby to receive breast milk, formula, or certain medications directly into the stomach when they are not yet able to take everything they need by mouth.
OG tubes are commonly used in premature babies whose feeding skills are still developing.
Why Might My Baby Need an OG Tube?
Premature babies are still learning how to coordinate sucking, swallowing, and breathing.
An OG tube allows your baby to receive the nutrition needed for growth while these important skills continue to mature.
OG tubes may also be used when:
Your baby becomes tired during oral feedings.
Your baby is receiving respiratory support, such as CPAP.
Your baby is not yet developmentally ready to breastfeed or bottle-feed.
Your baby needs additional nutrition beyond what they can safely take by mouth.
What Is the Difference Between an OG Tube and an NG Tube?
Both tubes deliver nutrition directly into the stomach. The main difference is how they enter the body.
OG Tube: Enters through the mouth and travels into the stomach.
NG Tube: Enters through the nose and travels into the stomach.
Your baby's care team determines which tube is most appropriate based on your baby's individual needs and respiratory support.
Will My Baby Always Need a Feeding Tube?
For many premature babies, feeding tubes are temporary.
As your baby grows and develops stronger feeding skills, the NICU team will assess readiness for breastfeeding or bottle-feeding.
Some babies begin taking small amounts by mouth while continuing to receive the remainder through their feeding tube.
This gradual transition allows your baby to practice feeding without becoming overly tired.
What Should Parents Know?
Having an OG tube does not mean your baby cannot learn to breastfeed or bottle-feed.
It provides important nutritional support while your baby develops the coordination and endurance needed for oral feeding.
Depending on your baby's condition, you may be able to participate in feeding-related care, including skin-to-skin holding, offering a pacifier, and providing expressed breast milk.
Every baby develops feeding skills at their own pace.
