Thoughts on the coloplast brava skin barrier protective sheets?

My sons skin flared up worse then it ever has before. The odd thing is that no leak happened before the rash appeared. Nothing will stick to his skin at all. So I did my usual to help the skin and that isn't working. Was wondering if anyone has used the protective sheets in this situation and it helped the bag stick ? His ostomy nurse had given me the usual advice but nothing is working. I've gone through 6 bags since yesterday.
