At What Age Should Children Learn First Aid?

My good friend Roddy and I are planning on teaching children first aid. More from a military-type of perspective but a kinder, gentler version for children. Making it fun, but challenging at the same time. Not only covering basics like stopping a bleed and bandages, but how to control fear; dial 911 and what to say; how to talk to victim, etc. We plan on putting together instructional videos and also offering live training. We bring over seven decades of combined experience as Central Intelligence Agency Operations Officers. This is still a work in progress, but here is a video trailer outlining our intent. If you are interested, in live training, please contact me at: ram@guardwelldefense.com.
