sounds like she may be allergic to the chlorine. make sure she showers when she gets home and gets out of the wet bathing suit right away. wash her suit. there may be a build up of chlorine in her swim suit and she may be sensitive. try some bendryll and see if that helps with the irritation. I would also try some hyrdocortisone cream instead of the neosporin. if that does not help make an appointment with the doctor.
