Oh. Substantially less risk vs scuba for sure, but still a fair amount of risk. Babies and toddlers have a reflex that will prevent them from inhaling water when submerged, a phenomenon known as infant swimming or baby swimming. However, they are not capable of "intentionally" holding their breath, and they are not physically strong enough to swim, which is why kiddie pools are so shallow, and so on.I'm sorry , I should've been more clear! The 2 year old wasn't on a tank. Just freedive. The dad took him down like 8 or 10 feet and took him up. U guys think there's any risk to that?
However, there are still risks involved with the pressure gradient -- 10 feet is enough for adults to have issues with clearing their eustachian tubes, for example. Not sure if babies are affected more or less by this type of stuff, but I'd be concerned.
