My 3 year old twins both have a bump on their butts..it is a very hard swollen bump and when u squeeze it yellowish pus comes out..I m not sure it they were bit by something. The male twin I noticed it yesterday and he said he hit the couch but when I noticed his twin sister had one tonight I am really concerned.its not in the exact same spot but both on their butts.
Dear parent, this is due to staph aureus infection. You need to clean the area very well with soap and water the Chat Doctor.
