My sister and I are both AP with our kids but I wouldn't say I follow a parenting method. I read half a Dr. Sears book once. Mostly, I just do what comes naturally which I suspect a lot of AP mamas do.
The other day, my mother (who was an AP parent herself before such a term even existed) asked what AP was. I was at a loss to effectively explain because its not like I actually follow a "method."
