I was changing my 2 year old daughter s (Will be three in October, 28lbs, Very healthy, Never any medical problems except common cold, flu, etc) diaper this afternoon & noticed her anus had a purplish hue to it and a red rind around it. This is not at all normal for her and up until about a half hour ago she seemed 100% fine with no issues in BMs or. Currently she is very upset, but I cant tell if she it is because she is in pain or for another reason (overtired). Any advice you could give on what this could be would be very helpful.
