I feel like I've heard/read enough to know that bumpers are generally a no-no, but what are people's thoughts on teething bumpers? Like this one? http://www.etsy.com/listing/122645204/10-x-51-crib-teething-bumper-grey-white?ref=sr_gallery_7&ga_search_query=chevron+teething&ga_view_type=gallery&ga_ship_to=US&ga_search_type=all

I think they are adorable and I like them from a design perspective, but my hunch is that they could come undone and pose similar risks to crib bumpers...even if they are higher up and out of reach of an infant. Thoughts?
