<human>: My 5 year old grandson just told me a gross thing was happening to him. It was penile erection. Apparently it happened before in front of his female playmates and they told him it was gross. I told him that it was nothing to worry about that sometimes it happens and to ignore it. Was this the right thing to do?
<bot>: Hello, Erection in kids, especially babies are just uncontrolled reactions of a healthy nervous system and parents need not worry about them.  So there is no reason for parents to believe that the erection is a result of sexual stimulation. Arianism is when your child has an erection that lasts 4 hours or longer. The erection may occur without stimulation.  Your children penis may be dark red or purplish. Arianism is usually painful and can lead to permanent tissue damage. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  V. Anand, Psychologist
