I hate freakin diaper rashes

So emmas reflux study came back really good.. which i think is because we just switched her milk. her gas has gone down by like 75%.. but now she has a bleeding but rash.. we have tried 2 types of anitfungal creams not working so now im trying letting her just be naked.. she seems happy about it.. just laying there laughing.. I hope it works.. she is in so much pain.. plus i think shes getting another upper respritory infection again.. i wonder what causes that.. who knows.. I think Im gonna try maloxx on her but i dont know what else to do its been like 2 weeks..i'm thinking about getting her a lil potty chair so she can have somewhere to sit and air out, as im typing shes smacking her but and so happy.. I wish she could cruise the house how much airing out can you do when your sitting on a towel.. owell..
