Oh the Irony! Parenting Video Parallels Polyamory

Update: Twice now the video below has disappeared from YouTube. I've just discovered it on another diaper company website. Should the video below disappear yet again, you can (hopefully) also see it here.
-------------------------------

My daughter, who is the mother of two small children and to whom I am out as poly, just sent me this video. I am amazed and delighted, though also a bit bemused. Many a poly person has under analogous circumstances had a very similar conversation with a significant other. Of course, not adding a new partner until existing partners give their consent is a much better and more ethical strategy, but that would ruin the gag here.

The video originally appeared on a diaper company's website in the UK (not anymore) and also appears on a second diaper company's site. Surely only a poly or poly-aware person would choose this approach for an educational video for parents who are working out how to introduce a child to a new sibling. It would seem that someone at the diaper companies (or their ad agencies) sees it as a cool way of attracting today's generation of parents with young children.

Could it be that polyamory really is beginning to infiltrate western mainstream culture to such an extent as this???
