How do i keep 3 month old baby from dislodging ng feeding tube?

Appropriate taping: Placing tape round actual tube after splitting it down the middle so half can go around in one direction and half the other direction, then securing under nose and a final piece of tape on the cheek to the side it goes to. If your pediatrician or their nurse can show you technique once, it's very helpful to actually see how the taping is done. May also need to pin hands to shirt to avoid grabbing.

Tape or a dressing: It is best to use tape or a dressing to guide the tube away from the nose and out of the way of the hands. Tucking the tube into the child's clothes may prevent it from being snagged when you are moving the baby. Be sure to learn how to replace the NG tube or consult your doctor if you need help putting it back into place.
