We put all 3 of our kids through ISR (Infant Swim Resource). they started at 9 months (based on summer relative to their birthdays). Its pretty incredible to see a 6-9 month old baby float indefinitely. At a year, they teach them to "swim, float, swim". The swim phase is targeted to 5-7 sec of holding their breath while swimming. https://www.youtube.com/watch?v=jeY9zYkNf7M https://www.youtube.com/watch?v=jeY9zYkNf7M
