TMI C section question

Ally

So I just had my son on the 8th via c section and, just like with my daughter in 2018, my incision has started getting a red heat rash around it from the belly hang. I know it’s best to keep it dry and clean and I do that! But I’m just wondering, can I put baby powder on it to help keep it dry? Or Vaseline or something? Thanks in advance! 😅
