@maique it’s terrifying - we completed a baby first aid course when our first was born but even then when my son started choking on a plum while with me at a zoo I totally panicked. Luckily he coughed it up by himself!
@maique in my school all Year 6 (10-11yr olds) complete CPR and basic first aid before they leave. The problem I think, based on my experience (I’m RTACC trained) is that unless you are in the emergency services you come out of the course confident to use it but slowly become less and less confident due to lack of use!
For those in the UK (and possibly other countries?) you can sign up-to GoodSam Responder. This will alert you when an ambulance is called out within a set distance of your location so you can get to them and start CPR. Been called out once so far using this app.
