Choking, I agree with you. CPR, no I don't think it's necessary to waste a whole day on this for a child-based course. It could be cut down to half a day easily.
Allergies and anaphylactic shock are more important, yet were glossed over. We really need to know the stuff we're most likely to encounter: head injuries, allergies, trauma injuries, bleeding, eye injuries, asthma and breathing difficulties - and much more information on babies.
A child is coughing and can't get their breath. Is it choking - or an allergic reaction? Both look similar.
I've a good idea of the difference because I've now seen both. I wouldn't if I'd just relied on what SJA told us (briefly, at the end of a 2 day course, most of which was spent on CPR).
And how many items in the first aid kit have we ever used? Plasters and the odd wadded bandage, I'll bet 
I'm told they put the triangular bandages in because they don't know what else to do with them
