Do you use capitals for the following "...a First Aid for Children course" ? or would the correct version be " a first aid for children course" ?

One more question - is this correct - "...your local Social Services' under-eights department..." ?

I'd be most grateful for a reply
Regarding your first question, I think if first aid is the name of the course, it can be capitalized. And I vote for non-capitalized initials in your second sentence. Let's wait and see what others have to say.

I'm also looking for an answer about first aid with or without capitals. But my sentence it is: "I was in charge of the First Aid procedures."
