My daughter who is 2 1/2 years old was complaining it "hurt down there" when I was changing her diaper. When I inspected more closely I noticed moderate redness in the perineal area. She has also been more clingy and quiet since then. Any thoughts on whether this should be followed up with a physician immediately or on what might be going on? I'm trying not to over-react, but would like to be as prudent as possible. She's just started potty training and is very enthusiastic about using the toilet paper.

Thank you for your thoughts.
