Diaper rash blisters?

Mandy

Hey all! I have a two week old baby girl and she has a diaper rash with little teeny blisters what can I do to make it go away? I change her almost right away when she goes and I’m using Desitin the purple one and changed her diapers :/ I’m at a loss. We have a son who is almost 2 and it’s a complete different diaper change than him. Still getting used to it!
