Diaper Rash Worsen

Hello po I already consulted my pedia tapos my ointment ng binagay at medyo pricey combiderm ata yun worth 400 plus pero di nag effect. I tried also petroleum jelly, fissan, calmoseptine, rashfree bumabalik parin ang rashes ng baby ko to think 1 month old pa sya. From pampers to EQ na din ako pero wala pa rin and nag lampin lang ako sa morning. And I always check her diaper and change immediately if may ihi or konting poop Help naman po anong other ointment or home remedy sa rashes ng baby ko, I am so worried.
