Another few things I would add to your list of parenting techniques Spidress are, distraction - change the subject/item being played with or talked about and positivity is vital. I try and never say no or don't. I focus on something they are doing better - "oh look at how well DD is holding her fork Daddy - well done". If I am asked if we can do something or buy something I have no intention of doing at the moment I tend to say something like - well that's an idea but remember if we do/get that you would have to miss out on ..... or something along those likes but I always reply by making them think that at least I have taken their idea into account and haven't just dismissed it out of hand. If that makes sense.
I do use "distraction" a lot, much more than "ignore" and since Incy has no real grasp of "time" yet and he normally says "maybe tomorrow" ie if we did everything "tomorrow" like he suggests we would need a 1,000 hour day I often use his phraseology and say things like "maybe tomorrow" or "perhaps next week" as generally he has forgotten about whatever his latest whim has said he "wants" not long after saying he "wants" it
