Have you tried to push the red tissue back inside the vent? Are you putting honey or Preparation H on it? Plain sugar with a couple of drops of water will work in a pinch to help the swelling go down. If the vent won't go back in easily, a little vegetable or olive oil will help. The longer it stays out, the tissue can dry out, and die. The prolapse can occur over and over for days, but just push it back inside and hold it as Sarevan instructed. Keeping her bottom washed off and clean will also help. Let us know how it's going.
