All I could say when I saw this viral baby yoga video (click on link to see it) was OMG, OMG, OMG. That is just an insane way to handle a two-week old baby, and probably borders on child abuse. It is at least child endangerment because even in expert hands something could go terribly wrong. I wouldn't even venture to do that with my 18-month old.
We'll stick to down dog.
