I was just changing my 15 month olds diaper and felt a bump on the side of his thigh, I looked and it's a small (1cm across) fluid filled blister. What is this? How would he get a blister there? I don't know how it could be a burn (I think I would have noticed that happen). Maybe an allergy? But we were inside all day, what allergen would cause a random blister on the thigh? Is there anything else it could be?
