Pamper swaddlers to cruisers?

Has anybody ever switched from Pampers swaddlers to cruisers and notice diaper rash? She's been in swaddlers since birth with no issues. We switched to cruisers this week (almost 5 months old) and now she has diaper rash. I can't think of any other changes but I also don't see any differences between the two other than shape when I search online.
