She does this, all while holding on to a toy! I’ve watched this vid a few times and I still find myself holding my breath.

Elizabeth’s parents posted the following to YouTube:

Just so everyone knows, I am a registered nurse and my wife was a life guard for six years and taught swimming for three. Not only are we both professionally trained in CPR and water safety, I am certified in advanced pediatric life support. The child in the video (Elizabeth) has been trained properly by ISR certified instructors.
