I trust I'm not alone in finding this sort of thing rather disturbing?

Seriously. It gives me 57 flavours of the creeps. I mean, babies, cute, yes. Babies rock cutedom, stinky nappies notwithstanding. Kids in animal costumes, yes. Many kids like animal costumes and will request or manufacture said costumes as part of creative play, free xpression, ect etc.

But this whole dressing babies up as stuff... it's just yuck.
