Is it child abuse or just a fake?

A bizarre YouTube video showing a woman casually flinging a young baby around by its ankles and wrists has got cringing viewers hoping that its a hoax.

The video, entitled "Baby Yoga with Lena Fokina" has become an Internet phenomena as viewers try to determine its authenticity.

"THIS IS ABUSE," writes on person on the YouTube site.  "I can't even watch this.  This woman should be arrested or educated."

Others speculate on the myriad of ways the child could be harmed or killed.

At the beginning and the end of the ‘yoga’ footage the baby looks real and appears to be moving around on its own.

But others are calling it a fake.

Definitely don't try this one at home.
