Yes it is! I would still have your pedi look just in case though.
usually its the hormones coming out of her, it happens in boys too, but ask the doctor just be to sure.
I would take her to her pediatrician just to be safe about it. My daughter never had that so I'm not sure if it's normal
they said it could happen when i took my girl in for her 1 week its just hormones from us mommas, they also said girls can have a little spotting over like 2 or 3 days its apparently their first period.
