It comes and goes. That was taken a few days ago and her stains were really light. Today her eyes have teared a lot and they are dark. She's only lost her top and bottom 4 teeth and is still chewing like crazy so I'm pretty sure it's the teething that's making her stains worse some days more than others.awww me too! what a cutie is her staining clearing up or is it just because it's in b&w?
