I love them. Why it so bothersome? It's pagan fashion.
It's also the return of a trend from late 70's/early 80's.
When I was a very little girl, I had a silver hair clip with purple-dyed feathers attached.
I'm not sure why you consider it odd if people adorn their two year olds, either. Depending on culture, little girls may have feathers, ribbons, flowers, ear piercings, or a pigtail on either side of their head. So what?
