The docs told me to use vaseline
Your pediatrician can prescribe Nystatin for her. She may be allergic to the diapers or wipes like the other ladies are saying and/or allergic to something you're eating seeing as you're breastfeeding. Good luck!! You can also try running water over her instead of continuous wipes and just do one final wipe before the next diaper
Make sure to keep her clean and dry. Bath her before bed time and use burst bees diaper rash ointment. With my daughter she rarely got diaper rash but when she did it sees nothing would make it go away we literally bought a bottle of every ointment and burst bees was the only thing that would make a difference. Walmart and target have it. A bit expensive around $10 for a small bottle
Try changin diaper brands and we use beaudrexs butt cream i think its spelled.
Go to your pharmacy and order RESINOL. My mom used it on us and I use it on mine. My youngest had a horrific rash from spaghetti sauce and she got raw and blistered so I put RESINOL on at each change it was cleared in 3 days.
Try Vagisil. It might be a yeast-based infection.
Change diaper brands she could be allergic to them
Bepanthan is good or sudocrem. Also I just put talc on my little mans bum if it gets bad as it helps dry out. Maybe change the type of nappie you are using. Maybe her skin doesnt agree with it. X
