So we took my daughter to the park today and she developed a bright red rash on her buttcheek/back of her thigh. She but scoots since she can’t walk yet and she was scooting through the grass, the rash is only on one leg tho. She also went on the slide and scooted around the playground but it didn’t feel hot enough to leave a burn. She also doesn’t seem bothered by it at all, it just looks really bad. Has this ever happened to anyone before? Should I be concerned? I’m hoping it continues to not bother her so she can have a good nights sleep but I am a little worried. Fingers crossed it’s gone by morning.
