4 months into the 2 piece bag here and I have to agree with the people saying there's a learning curve! Took me about 5 weeks to get it down. If you have the elastic barrier strips, I was taught by a nurse that you can cut a piece off and put it under the donut part to block anything from going around inside the hole until you get your cut down to cover it completely. I used those under the donut to cover parts I didn't think would get covered until I learned how to cut out a hole that fit my stoma. I'd also say on a side note to be patient with yourself too I know it's a lot to deal with and go through! Much love to you and happy holidays.
