Reoccurring infection on penis

Caitlin

My almost 18 month old has had an infection on his penis before. We bathe him ever other day and keep him clean otherwise. He's also had a fungal infection on his scrotum. We've taken him to the Dr and they tell us what to do and we obey. WHY DOES THIS KEEP HAPPENING 😩😩 now tonight as we gave him a bath, it looks like he's getting an infection like he's had before AGAIN! I'm planning to call right away tomorrow to get him looked at. Does this happen to anyone else!? I feel awful for him! I just don't understand why this keeps happening over and over!
