3 month old not a rash

Stephanie

My 3 month old baby girl has been red on her outer labia around the top for a couple days not a rash.. not bumpy or anything. It's been kept clean and dry inner and outer. Tried sudocream but not better or worse any help mamas ?

I've got one of those crib pee pad things (like puppy pads) should I let her air it out for a little bit? Is that something that would help?
