Aloe Vera on diaper rash?

Taylor

Has anyone used aloe Vera plant on diaper rash or milk of magnesium? My son has terrible diaper rashes and we’ve been to the doctor multiple times and have gotten 4 different prescription creams and none are working this time. They said to use Vaseline but it not helping the irritated skin it’s helping keep the poop off. He’s on antibiotics for an ear infection and he’s had diarrhea ever since having that and the diaper rash is getting worse. He has been changed 3 times in last hour with poop every time. Any other things I can try since the doctor we see isn’t helping?????????
