@swimperfect.co: Can your 3 year old keep their head above water and tread and then float? This could save their life! This is how I introduce treading, while always giving them the option to rest back in the float. The best part? They can breathe, call for help, or take a break before finding the wall or steps. This is perfect for those who already know how to do pop up breaths and floats! #misscallie #watersafety #swimlessons #treadingwater #childledswim
