Hands down w/out a doubt I recommend you do Infant Swimming Rescue with Sherri Phillips - ###-###-#### - ____@____.com - it's more about an infant learning to rescue themselves if they fall in - she teaches them to flip to their back and swim to the side - I took my 10 month old last year and it was amazing to watch - I'm going back in May to do a refresher class for 6 weeks w/him - Sherri is an absolute professional and will take the best care of yoru child. You can find our more about her and the ISR program here: http://www.infantswim.com/
I passionately believe in this program - I believe it saves children's lives. Please let her know C. Walker sent you her way if you decide to use her. :) Best of luck!
