My little girl was like that, but she just has a high pain tollerance, like me. If she had a problem with her reflexes they would have caught it when she was born when they tested her APGAR. Bring it up when you see your pediatrition next time and they'll help you figure it out. The best over the counter thing I found for diaper rash is Aveeno diaper rash cream. It's amazing! If you are still having a hard time with rash, try coating the diaper with some original maalox before you put it on, in addition to the rash cream. I've also tried mixing the maalox with the rash cream, that works too. Good luck!
