My grandson was born with a small natal crack above his natural one, the doctors say it was probably because the lower spinal area did not close over completely or something, but it was very minor and nothing to worry about. However, now he is 2, and that area is bleeding and sore right where that upper crack is. He also frequently gets yeast-type infections in the genital area and the skin around his penis is often red and raw looking. There is absolutely NO chance of any type of sexual abuse, this is strictly a diaper-issue. What is the best way to heal this, and should we be concerned?
