Hi. My baby has a rash near her anus. It doesn't seem like diaper rash coz we rarely use diapers. It was small in the beginning. But it seems to be bigger now. it's red, around her anus and seems to grow bigger. Her pead said tat it's diaper rash and recommended liquid paraffin.. but it's of no use. the rash seems the same. I've also tried lacto calamine but even this doesn't help much. Wat is the remedy?
