J.S.
Like with any parenting aid, I think it has its place and has some valuable advice. I take what works and toss the rest, just like with attachment parenting and just like with other self-proclaimed parenting "styles." I don't subscribe to a particular parenting style because labeling a parenting style narrows things into a little box and you end up feeling like you have to stick with that one particular way whether it all completely works or not.
Mostly it depends on each of my children and their personalities and their needs. They each respond differently to different discipline techniques and different parenting tools so I have to be flexible.
