My daughter is 12 weeks old and her BCG injection site is not looking so good. It's been raised up and red for over a month (the nurse told me that was fine last time we went in for her injections). A few days ago I noticed it looked like it was full of something and tonight it ruptured in the bath and all this pus came oozing out, then blood...is this normal? I'm worried it's going to leave a nasty scar. I'm not sure if I should I put gauze over it, or let it breathe?? I will call the clinic tomorrow, but curious to hear any other experiences...
