My son was born with swollen balls that slowly shrank down but his ballsack was still loose like old man balls. Then suddenly we change him this afternoon and it's all tightened up and no more loose skin. Inbetween the space of 30 minutes. (we changed him once for poop, then he pooped again 30 mins later and his balls are magically tight and no longer saggy) is this normal to happen so suddenly? I tried searching online for any information but I can't seem to find anything on this. Has anyone had this happen before?
