I have an intact 18 mo, he is my fourth intact boy and I thought I had seen everything. Tonight ds was obviously in pain and when I got him ready for bed I saw that his penis was swollen-- not the foreskin, but the whole thing, bulging on one side. Color is not bright red but maybe "flushed." A bit of milky moisture at the opening. So I would say a smegma pearl is working itself out...but for the pain? It doesn't look like yeast on the outside or anything.Could that be it? With the pain? I am checking in a little while to make sure he is wetting his diaper because I couldn't tell if he peed when I put him in the warm water.TIA, mamas.
