[quote=Anonymous]I hope this helps you understand the risk.  It draws from statistics in Australia.  You are doing your family a huge favor by enrolling in swim lessons.

The National Drowning Report 2023 shows that 281 people drowned in Australian waterways.  
77% of drowning deaths were male and 57% were over the age of 45 years.  Many were immigrants who did not know how to swim.

Statistics drawn from the Royal Life Saving National (Australia) Fatal Drowning Database, based on cases from the Australian National Coronial Information System showed:

There were fewer than 2 deaths per year related to hypoxic blackout. Between 1 July 2002 and 30 June 2015, hypoxic blackout was implicated in 22 drowning deaths. All involved males; 17 were aged 18–34 years. The most common scenarios were recreation in domestic or public swimming pools (12 cases) and diving in ocean or harbour locations (nine cases: five while spearfishing, four while freediving). Four of those who drowned in swimming pools had pre-existing medical conditions (predominantly cardiac conditions), and blood alcohol levels exceeded 0.05 g/dL in three.[/quote]
