As DM, how much should I coach a party (composed entirely of brand new players) to consider things like assigning someone to stand watch while the party sleeps, covering/hiding provisions, recovering arrows, checking for traps, considering interrogation rather than just killing enemies, etc? These are things a novice usually picks up from adventuring alongside veteran players, but in this case, the DM is the only veteran.
My first thought is that this is a DM preference, and so far I have been letting the party make most of these (avoidable) mistakes so they can grow wiser on their own. That's what "experience" points are for, right? But I wonder, at moments, if I'm being unnecessarily strict about that. A hint here and there, even if delivered slyly through an NPC's dialogue seems allowable, and could save them some heartache, just as learning from a seasoned gamer in their party would. Would this be cheating players of their chance to learn at their own rate, no matter the time & sweat required?
