Children do like order, rules and boundaries:
Now I can relate to it. Every time the order and routine is altered, I had noticed them acting cranky. Sleeping pattern, feeding pattern, play time .... I get it. Discipline in fact starts right from there I guess
Conversation:
I do now recollect a relative who had never raised hand at his daughter. Even though she is very naughty she always listens to her dad! (that puts off her mom though). I think the real challenge here is the patience and perseverance and involvement of the adult.... which is the key
Skills:
I remember reading about "redirection" method used by Killer Whale Trainers. And I had seen people doing it with their kids but in slightly silly manner. What I had witnessed looks like "diverting" or "distracting" them rather than redirection

I need to understand the redirection more clearly - I will do that home work.
Are there workshops for expecting parents or parents with new borns on such skills? Sounds like an amazing thing to do

Well I guess training kids are much easier than training adults...
snowy, you are right. I had seen my close friends who are now parents... They act really weird at times. May be I need to become a parent to get that weird
