I have a male baby about 3/4 weeks old that came to me last week. His brother ended up trying to nurse on him and well caused his penis to swell and scab over. (They have been apart since incident) got the scab off and he was using the bathroom last night. Woke up this morning for a feed and saw that his penis is more swollen with what appears to be a blister on the shaft itself. While I was cleaning him from a BM the "blister" popped and fluid is coming out. I have left a message with an experienced rehabbed and I'm just waiting for her to call me back.
