Riya's Rash

This morning, as I was getting Riya dressed, I noticed a few little red patches on her skin but didn't think much of them because she has somewhat sensitive skin and usually it's nothing. By this evening, she was showing signs on her neck, legs and arms. I quickly lifted her shirt and saw this - and there was more on her other side. It looks to me like the reaction she sometimes has from bug bites but it didn't make sense because it wasn't there (like that!) this morning - when I first saw red.
She wasn't complaining of itching or anything but she did think the rash was fascinating! She stood on the chair by the sink, topless just staring at her rash... turning and twisting so she could see it all.
We decided to give her a bath and change her bedding and see how she did. The bath seemed to help - the rash was already fading by the time she got pajamas on.
Who knows - but if there is a rash to get, Riya will probably get it. She got them often when she was an infant and they are so hard to diagnose that I usually don't even take her in unless it becomes more than just a rash. She seems fine for now!
