Potty Training: Neocate

4 Year Old Potty Trained W/diaper Rash????

My son has allergies and sensitve skin. He has gotten some pretty nastey diaper rashes in the past. He's been potty trained for almost 2 years. But frequently he complains of his butt itching and begs me to Whipe him (and i don't do more than necessary). His butt area around his anus gets very red and sometimes there's teeny tiny bit of blood when he whipes... from that skin. We thought maybe he wasn't doing a clean enough job himself so we do the 'finishing touch'. Now we are considering the desposable whipes but i'm fearful it has to...
