A G-tube is a feeding tube placed directly into your child's stomach through a small opening in the abdomen. It delivers food, fluids, and medications when a child can't eat enough by mouth safely or consistently.
If your child's doctor just brought this up, you probably have a dozen questions. That's normal. Most parents feel a mix of worry and confusion the first time they hear the words "gastrostomy tube." This guide covers everything you need to know: what a G-tube is, why your child might need one, how it works, what daily life looks like, and when to call the doctor.
How a G-Tube Works
The full medical name is gastrostomy tube. "Gastro" means stomach. "Stomy" means opening. A surgeon creates a small opening (called a stoma) in your child's abdominal wall that connects directly to the stomach. The tube sits in that opening.
Everything your child needs nutritionally goes through the tube: formula, blended food, water, and medications. The tube bypasses the mouth and throat entirely. Your child's stomach still digests food the same way it would with oral eating.
A G-tube doesn't replace the stomach. It simply creates a new way to get nutrition into it.
Why Children Need G-Tubes
Children need G-tubes for many different reasons. Some are temporary. Others are long-term. The common thread is that eating by mouth alone isn't safe or sufficient.
Neurological conditions. Children with cerebral palsy, brain injuries, or other neurological conditions may have trouble coordinating the muscles needed to swallow safely. Food can go into the lungs instead of the stomach, which causes aspiration pneumonia.
Premature birth. Babies born very early sometimes haven't developed the suck-swallow-breathe coordination needed to eat by mouth. A G-tube bridges the gap while they catch up.
Congenital conditions. Some children are born with structural differences in the mouth, throat, or esophagus that make swallowing difficult or impossible.
Failure to thrive. When a child isn't gaining weight or growing despite every effort, a G-tube ensures they get the calories and nutrients their body needs.
Metabolic or genetic conditions. Some conditions require very specific nutrition delivery, precise calorie counts, or continuous feeds that aren't possible by mouth.
Recovery from surgery or illness. Some children need a G-tube temporarily while healing from a major procedure or illness. The tube comes out once they can eat safely again.
The decision to place a G-tube is never made lightly. Your child's care team, including the pediatrician, GI specialist, and often a feeding therapist, will evaluate whether a G-tube is the right step.
Types of G-Tubes
Not all G-tubes look the same. The type your child gets depends on their age, medical needs, and how long they'll need the tube.
PEG Tube
PEG stands for Percutaneous Endoscopic Gastrostomy. This is usually the first type of G-tube a child receives. It's placed using an endoscope (a small camera guided through the mouth into the stomach) and looks like a long, flexible tube extending several inches from the belly.
PEG tubes are temporary. Most children keep one for 8 to 12 weeks while the stoma heals and forms a stable tract. After that, doctors typically replace it with a low-profile button.
For a full comparison of PEG tubes and other G-tube types, read our guide: PEG Tube vs G-Tube: What's the Difference?
Low-Profile Button
After the stoma matures, most children switch to a G-tube button. Common brands include MIC-KEY and AMT Mini ONE.
A button sits nearly flush with the skin. It's small, capped when not in use, and mostly hidden under clothing. To feed, you connect an extension set to the button, deliver the formula or food, then disconnect and close the cap.
For active kids, the button is far more practical than a PEG tube. It's harder to pull out accidentally, easier to manage during play, and more comfortable for sleep.
Surgically Placed G-Tube
Some children receive a G-tube placed through a small surgical incision (sometimes laparoscopically) rather than endoscopically. The approach depends on your child's anatomy and medical history. The end result is the same: a tube or button in the stomach for feeding.
How a G-Tube Is Placed
G-tube placement is a surgical procedure done under general anesthesia. Most placements are outpatient, meaning your child goes home the same day or the next morning.
The procedure typically takes 30 to 45 minutes. Your GI doctor or surgeon will explain the specific approach beforehand, whether that's an endoscopic (PEG) placement or a surgical one.
After placement, your child will have some soreness at the site. The care team will teach you how to clean the stoma, manage the tube, start feeds, and watch for signs of infection before you leave the hospital.

Daily Life With a G-Tube
This is the part most parents worry about the most. The reality: daily G-tube care becomes routine faster than you'd expect.
Feeding
G-tube feeds happen in a few different ways depending on your child's needs:
Bolus feeds deliver a set amount of formula over 15 to 30 minutes using a syringe. This mimics a regular meal schedule. Most children on bolus feeds eat 4 to 6 times a day.
Continuous feeds use a pump to deliver formula slowly over several hours, often overnight. Children with reflux, delayed gastric emptying, or other sensitivities may do better with continuous feeds.
Blended diet is an option some families choose with their doctor's approval. Real food is blended smooth enough to pass through the tube. Not every child is a candidate, but it's worth discussing with your GI team.
Your child's dietitian will set the formula type, volume, and schedule. As your child grows, these will be adjusted.
Site Care
Keeping the stoma clean and healthy is the most important daily task. The basics:
- Clean around the stoma once or twice a day with warm water and a soft cloth
- Check the skin for redness, swelling, drainage, or granulation tissue
- Make sure the tube or button sits properly and isn't being pulled by clothing or movement
- Rotate the button gently (per your doctor's instructions) to prevent the tract from narrowing

Medications
Most liquid medications can go through a G-tube. Some pills can be crushed and dissolved. Always check with your pharmacist before putting any medication through the tube, because some should not be crushed and some can clog the tube.
Flush the tube with water before and after each medication to prevent blockages.
Common Concerns
"Will my child still be able to eat by mouth?"
Many children with G-tubes also eat some food by mouth. The tube supplements what they can't get orally. Some children work with feeding therapists to build oral skills over time and may eventually transition off the tube entirely. Others use the tube long-term alongside some oral eating. Your child's team will guide this process.
"Can my child go to daycare or school?"
Yes, but the setting matters. Standard daycares aren't equipped to manage tube feedings and stoma care. Your child needs a program with trained medical staff.
PPEC (Prescribed Pediatric Extended Care) centers are built for exactly this. Licensed nurses handle G-tube feedings, site care, and medication delivery throughout the day. Your child also receives developmental therapies and gets to socialize with other children in a safe, medically supervised environment.

"What about baths and swimming?"
Once the stoma is fully healed (usually 6 to 8 weeks after placement), most children can take baths and swim. Buttons handle water better than PEG tubes because there's no external tubing to manage. Ask your GI doctor when it's safe for your child specifically.
"Is a G-tube permanent?"
Not always. Some children need one for a few months while recovering from surgery or catching up on growth. Others use one for years. When a child no longer needs the tube, the doctor removes it and the stoma typically closes on its own within a few days to weeks. A small number of children need a minor procedure to close it.
"What if the tube falls out?"
With a PEG tube, this is rare because of the internal bumper. With a button, it can happen, especially with active toddlers. The stoma can begin closing within a few hours, so you need to act quickly. Your GI team will give you an emergency plan and a spare button to keep at home.

When to Call the Doctor
Contact your child's GI team or pediatrician if you notice:
- Redness, swelling, or warmth around the stoma that's getting worse
- Pus or foul-smelling drainage from the site
- Granulation tissue (raised, red, moist tissue around the stoma) that doesn't respond to home treatment
- Leaking around the tube during or between feeds
- The tube or button has come out and you can't replace it
- Persistent vomiting or retching during or after feeds
- Fever with no other obvious cause
- Pain at the site that doesn't improve with positioning changes
- Tube blockage you can't clear with warm water flushes
When in doubt, call. Your GI team would rather hear from you early than late.

Frequently Asked Questions
What does G-tube stand for?
G-tube is short for gastrostomy tube. "Gastro" means stomach and "stomy" means opening. It's a feeding tube placed through a small opening in the abdomen directly into the stomach, allowing food, fluids, and medications to bypass the mouth and throat.
What is the difference between a G-tube and a PEG tube?
A G-tube is the general term for any gastrostomy tube. A PEG tube is one specific type of G-tube, named after the placement method: Percutaneous Endoscopic Gastrostomy. All PEG tubes are G-tubes, but not all G-tubes are PEG tubes. Some are placed surgically. For a detailed comparison, see our PEG Tube vs G-Tube guide.
How long does a G-tube last?
The initial PEG tube stays in for 8 to 12 weeks. After that, most children switch to a low-profile button that gets replaced every 3 to 6 months. How long your child needs a G-tube overall depends on their condition. Some children use one for months, others for years.
Can a child with a G-tube eat food by mouth?
Many children with G-tubes eat some food by mouth. The tube supplements what they can't get orally. Some children work with feeding therapists to develop oral eating skills and may eventually stop needing the tube. Others use both oral eating and tube feeding long-term.
Is G-tube placement surgery risky?
G-tube placement is one of the most common pediatric procedures. Serious complications are rare. The most common issues are minor: skin irritation, granulation tissue, or temporary soreness at the site. Your surgeon will discuss the specific risks for your child before the procedure.
What does a G-tube fed child eat?
Children with G-tubes receive nutrition through specialized pediatric formulas, and some families use blended real food with their doctor's approval. The formula type, volume, and feeding schedule are set by your child's dietitian based on age, weight, and nutritional needs. Feeds can be delivered by syringe (bolus feeds) or by pump (continuous feeds).
Can you go to daycare with a G-tube?
Yes, but not at a standard daycare. Children with G-tubes need a program with licensed medical staff who can manage feedings, medications, and stoma care. PPEC centers specialize in caring for children with medical needs like G-tubes. Learn how PPEC helps children with G-tubes.
