Our daughter was coughing after swimming in a river a few weeks ago, and my mother in law found the dry drowning stuff on the internet. I was like "dry drowning doesn't exist," but we called a nursing hotline which told us to go to the ER. The doctor checked out the kid, then asked us for the number of the nursing hotline so she could yell at them for sending parents to the ER over a condition that doesn't exist.
No shit swallowing water is not the same as aspirating [breathing] it and nobody said it was!
"And I’m pretty sure everyone understands that a child who is down in the water, gets pulled out, and requires resuscitation needs immediate medical attention, even if they seem to recover." - No, they might not!!! And that's the point!!!
The takeaway is:
If someone has a serious near-drowning episode they should seek medical attention even if they appear fine.
If someone exhibits symptoms listed after aspirating water, they should seek medical attention.
His doctor contradicted you, and the advice you gave at the end of your comment. Are you also a doctor?
We just got done doing a swimming class for our 2 year old and this was addressed in the class. I highly recommend you take a class with your children. Classes for younger than 3 years old are done with parents in the water. It'll make both your children and you much more comfortable and safe.

I'm speaking a little in hyperbole here, but you get the point I'm sure.
My mom was a great parent and wonderful overall, but that was a particularly excellent decision of hers. She was still careful with my little brother and me around water - we were enrolled in Red Cross swim classes during the summers in elementary school, and always had lifejackets on at the lake. Despite being terrible at pretty much all sports (unlike my athletically-gifted brother), I was always a decent swimmer.
When my wife and I were on our honeymoon we watched a couple throw their 6 month old (10 month maybe? wasn't walking, only crawling) in the pool over and over again. Most of the pool looked on in horror, but they had taught her the "leg kick to turn over onto her back and float" skill. Definitely gave us perspective.

"Any child pulled from the pool needs medical attention," says Dr. Berchelmann. "At the very least, call the pediatrician."
