There was a thread a while ago but I can't find it; most people seemed very skeptical of 'avoiding saying no' and equated it with letting kids run rampant or doing whatever they wanted.

I thought this post was nice and succinct, and gave some really specific reasons behind the idea: http://www.positiveparentingsolutions.com/parenting/simple-words-to-avoid-power-struggles

Don't worry, our parents think we're silly too, but we've been really thrilled and surprised at LO's general attitude, willingness to respect our boundaries/wishes and lack of tantrums so far at 16 months. I certainly don't think it's all because of what we're doing/not doing -- and don't want to come across like I think I'm a parenting genius who has it all figured out. But I thought I'd share since it had been brought up before!
