So, if you don't get the wafer right and you cut it too big you have exposed skin. Now think about what happens inside the bag: Pooh comes out of the center of the stoma and either drops into the bag or gets stuck around the reservoir that is the wafer. So, pooh can just sit on that exposed skin. You change the wafer like every 4 days or so.
This morning we changed it and all the skin around the stoma was red and like burning off! Eww is right! Thankfully we found this stuff that is supposed to create a crust- like a scab. Well it is a two step process and we were only doing one step- needless to say, it got pretty bad.
But we are all good to go now!! I love new wafer day! I feel so clean. :)
