What do I need to know about an infant having a g-tube?

Feeding Method. A gastrostomy tube (g-tube for short) is a small tube, held in place by a balloon that provides an opening to the stomach. It is usually used for liquid nutrition and medications in children who can not eat by mouth or who do not take in adequate nutrition by mouth. The most important thing to know is how to take care of it, keep the area clean, to give the child nutrition, and to replace it.
