My daughter, almost 2 1/2 years old, has been fussier than normal, complaining that her girl parts hurt. She has been pulling at it asking for diaper cream, upon doing this, I found her labia , or some part on her genital appears to be swollen, also a little red around the area. What could this be? At first, I thought a UTI ... either way, I should be taking her in immediately to be seen by a doctor?
