Belly Button

That famous belly button that Brady is so proud to show off is now infected.  I know how infections like that start, but I cannot figure out how Brady's got that way.  I feel so bad for him because it's all red, but it doesn't seem to bother him because every time I put the Polysporin on, he thinks I'm tickling him.  I think the part that bothers me the most is that I'm not sure how long these last and I don't want it to get worse.  Grrrr...  I don't like when things go wrong with my baby.  He also has the worst diaper rash he has ever had, so I wonder if it's connected or what is going on.
