Has anyone else experienced this? I've heard they are relatively common among infant boys, due to testosterone levels that peak around 2 to 3 months before mellowing out at 6 months. My son got his first one when he was about 7 weeks old. Thankfully it came to a head on its own and healed with the help of hot compresses after every nappy change and frequent baths. He's got two more now. Thankfully none have abscessed, but that's what I'm always worried will happen. Any tips for how to prevent them? Any creams that help? (We've been using Sudacrem). Any encouragement from mums whose baby boys had these for a while? When did they stop coming? He is my third son and none of the others got anal boils! In general, he's a very happy, healthy, big, sweaty, stinky baby. Definitely seems like he's got high testosterone!
