Saw a video online of a 2 year old being taken to bottom of a pool then back up. Pool looked to be 8 to 10 foot deep. The comments on the video of course were all over the place. Tried Google to see what depth would be an issue for a kid that young but there really wasn't any info. The two things I was thinking is the kid didn't know how to equalize that would be a problem. And second probably increasing risk for ear infections. Thoughts?
