Help! Baby Rash!

She’s never had a rash before. She’s 4 months old, formula fed, got her vaccines 5 days ago. She doesn’t have a fever, fussy but no more than usual. I tried putting aveeno eczema on it and as you can see it just got worse. No change in soap, creams, detergents etc. We haven’t started solids. Please help. FTM.
