What Is an NG Tube?
An NG tube (nasogastric tube) is a small, flexible feeding tube that passes through a baby's nose, down the esophagus, and into the stomach.
It allows the NICU team to provide breast milk, formula, or certain medications directly into your baby's stomach when they are not yet able to take everything they need by mouth.
NG tubes are commonly used for premature babies because the ability to coordinate sucking, swallowing, and breathing develops gradually.
Having an NG tube does not mean your baby cannot learn to breastfeed or bottle-feed. It simply provides nutritional support while those skills develop.
Why Does My Baby Need an NG Tube?
Premature babies may not yet have the coordination or endurance needed to complete all their feedings by mouth.
An NG tube may be used when a baby:
Is too premature to safely coordinate sucking, swallowing, and breathing
Becomes tired before finishing a feeding
Needs additional respiratory support
Has difficulty taking enough milk to support growth
Is temporarily unable to feed by mouth because of a medical condition
The feeding tube helps ensure your baby receives adequate nutrition without using more energy than they can comfortably manage.
How Is an NG Tube Placed?
A nurse or other trained healthcare professional gently passes the tube through one nostril, down the esophagus, and into the stomach.
The tube is then secured to your baby's cheek with special tape or a protective adhesive.
The healthcare team verifies that the tube is positioned correctly before using it for feedings.
Placement is checked according to NICU protocols, including reassessment when there is concern that the tube may have moved.
Although insertion can be uncomfortable and may briefly cause gagging or crying, the tube is soft and flexible.
The team uses appropriate comfort measures to help your baby tolerate the procedure.
How Does Feeding Through an NG Tube Work?
Milk is delivered through the tube directly into your baby's stomach.
This is called gavage feeding.
Feedings may be given slowly using a syringe and gravity or through a feeding pump.
The method and feeding schedule depend on your baby's medical condition and nutritional needs.
Some babies receive their entire feeding through the NG tube.
Others breastfeed or bottle-feed first and receive the remaining milk through the tube.
For example, if your baby is scheduled to receive 40 mL of milk and takes 25 mL by bottle, the remaining 15 mL may be given through the NG tube.
This allows your baby to practice feeding skills while still receiving the nutrition needed for growth.
Does an NG Tube Hurt My Baby?
Having an NG tube in place is generally well tolerated, although insertion and repositioning may cause temporary discomfort.
Some babies may experience mild irritation around the nose or cheek where the tube is secured.
The NICU team monitors the tube and surrounding skin for signs of irritation or other problems.
If your baby appears uncomfortable, let the nurse know.
Can My Baby Still Breastfeed or Bottle-Feed With an NG Tube?
Yes, when your baby is medically stable and developmentally ready.
Many babies begin practicing oral feedings while their NG tube remains in place.
Your baby may start by:
Practicing non-nutritive sucking
Spending time at the breast
Taking small amounts of milk by bottle or breast
Gradually increasing the amount taken by mouth
The NG tube provides additional nutrition while your baby develops coordination and stamina.
Learning to feed is a developmental process, not a race.
Some babies progress quickly, while others need more time and practice.
How Does the NICU Know When My Baby Is Ready to Feed by Mouth?
The healthcare team evaluates several factors, including:
Gestational and postmenstrual age
Breathing stability
Ability to coordinate sucking, swallowing, and breathing
Feeding cues and alertness
Endurance during feeding
Overall medical condition
Feeding readiness is not determined by age alone.
Your baby's nurse, neonatal provider, and feeding specialists may work together to develop an individualized feeding plan.
What Are Feeding Cues?
Feeding cues are behaviors that suggest your baby may be ready and interested in feeding.
These can include:
Bringing hands toward the mouth
Rooting or turning toward touch near the mouth
Sucking on fingers or a pacifier
Becoming quietly alert
Showing interest in the breast or bottle
The NICU team also watches for signs that your baby needs a break, such as changes in breathing, color, alertness, or coordination.
Responding to these cues helps support positive feeding experiences.
What Is the Difference Between an NG Tube and an OG Tube?
Both tubes deliver milk directly into the stomach.
The difference is where the tube enters the body.
NG Tube — Nasogastric Tube
Enters through the nose
Passes down the esophagus into the stomach
Commonly used for babies receiving tube feedings
OG Tube — Orogastric Tube
Enters through the mouth
Passes down the esophagus into the stomach
May be preferred for certain babies receiving respiratory support
The healthcare team chooses the type of tube based on your baby's needs.
Are There Risks Associated With an NG Tube?
NG tubes are commonly used in the NICU, but they require careful monitoring.
Potential concerns include:
Temporary discomfort during placement
Irritation of the nose or surrounding skin
Tube displacement
Incorrect tube positioning
Milk entering the airway if a misplaced tube is used
The NICU team follows established procedures to verify placement and reduce these risks.
Parents should never reposition or use an NG tube without appropriate training and guidance from their baby's healthcare team.
When Will My Baby's NG Tube Be Removed?
The NG tube is generally removed when your baby can consistently take enough nutrition by mouth while maintaining appropriate growth and clinical stability.
The healthcare team considers whether your baby can:
Feed safely
Take adequate volumes by breast or bottle
Maintain breathing stability during feedings
Demonstrate appropriate weight gain
Complete feedings without excessive fatigue
Some babies need their NG tube longer than others.
Occasionally, babies who still require tube feedings may go home with an NG tube and a carefully developed home-feeding plan.
If this is necessary, the healthcare team provides specific education and training before discharge.
Can Parents Participate in NG Tube Feedings?
Often, yes.
Many NICUs encourage parents to participate in feeding-related care.
Depending on your baby's condition and hospital policies, you may be able to:
Hold your baby during tube feedings
Provide breast milk
Offer a pacifier during feeding
Practice skin-to-skin care
Help recognize feeding cues
Participate in feeding routines with nursing guidance
These experiences can help you feel more involved in your baby's care while supporting bonding and development.
What Can Parents Ask?
If your baby has an NG tube, consider asking:
Why does my baby need an NG tube?
How much milk is my baby receiving?
Is my baby showing signs of readiness to feed by mouth?
Can I hold my baby during tube feedings?
Can my baby practice breastfeeding or bottle-feeding?
What milestones need to happen before the tube can be removed?
How can I help my baby develop feeding skills?
What Should Parents Know?
An NG tube is a temporary feeding tool that helps premature and medically fragile babies receive the nutrition they need.
It allows your baby to grow while developing the skills necessary for breastfeeding or bottle-feeding.
Needing an NG tube is not a setback. It is often a normal part of learning to feed in the NICU.
Every baby develops at their own pace, and your healthcare team will help guide the transition toward independent feeding.
