Soother rash

Br

Hey guys, my daughter has had a rash from her soother for the last week or so. I've kept it as dry as I can and I've been putting lotion on her cheeks as a barrier but it's still persisting.

Any tried and true methods? She doesn't have her soother all day long just for naps/bedtime and a bit in the morning.

I thought about using Vaseline as a better barrier but don't want to clog her little pores.

Hit me with your suggestions!
