Thanks guys I used the hydrocortisone cream.n it works perfect.
Corn starch works great, my family uses it too. Also after you shower try laying in a way that your breast are not covering the area to allow it to breath. Fresh air and air drying does wonders :)
You can get corn startch at walmart. Itd probably be in the food section just because you can use it for both. But yes it does work. My parents used it on me as a kid when i got any rashes.
Corn starch helps im not a mom yet but that's what everyone in my family uses for bad rashes and it works
