Good question and very thought provoking. I’ve been dreaming of the day when my 5 year old daughter is old enough to join me in the big blue. I never even thought about what would happen if "I" needed to be rescued! I suppose the decision will be a personal decision for each case, as everyone’s abilities and common sense are different. In my case, I am now considering that I will want my daughter to come with me AND another adult buddy just to be safe. Of course that will change as she grows as a diver. Plus I will get her a really loud whistle! :-) Thanks for the question.
