Hi Nana,
First, I hope you are able to keep yourself safe during this crazy pandemic. It is a scary time to be living in, especially with hospital visits.
I have not seen your question on this site before, but maybe some of the members who have been around longer will have, and have some sage advice for you. I would suggest that you start by looking at old forum topics, and see if that gives you any help. Your question is so broad that it's difficult to know how to answer. Puppyluv had some really good suggestions, and I'm sure others will as well. One suggestion I would make, and it's so darn obvious that I don't know why nobody at the hospital told me, has to do with softening the inside of the flange hole. After you cut the flange to fit over your stoma, you will want to slightly soften the inside of that hole. The easiest, and most efficient way is to put a damp washcloth over your finger, and use that finger to rub around the inside of the hole a few times. That will soften it, and prevent it from rubbing against your stoma and causing it to bleed. I have seen hospital staff use their finger, or the side of a scissor blade, but nothing works as well as a damp cloth over a finger. Nana, if you have any specific questions, ask away! We will do our best to help.
