Baby rash! Anyone seen one like this?

Molls

YES I’ve already talked to doctor (on Wednesday). I thought my boy was having a reaction to fabric softener. But it still isn’t going away. The DR saw pictures as well and said if it doesn’t get better after a couple days of using hydrocortisone to come in. Not better yet... but not worse either. The office is closed over the weekend. Not sure what this could be!
