Betty, the bags I use come from the same place I get the food. I think any medical supply place will have them. Better still, ask the nutritionist at the hospital. One does not need a special feeding tube. There is a tapered end to the tubing on the bag which slips right in tightly. There is a valve on the bag that regulates the rate of flow. It also helps to sit up straight while feeding. My instructions were to first take in a syringe of water, then the food, then more water. The bag must be changed every 24 hours. I think you are on the right track about slower feeding. Good luck!
