A mom who posted a video of her child's controversial swim lesson says she's now getting death threats. In the video, the instructor tosses an 8-month-old baby into the pool. A few seconds later, he surfaces, using his instincts to stay afloat. The boy's 3-year-old brother is also thrown into the pool before popping up. Onlookers cheer but social media is aghast. Krysta Meyer said she posted the videos to show how her sons were learning how to float in case they ever fall into a pool.
