I follow some of AP philosophy, but I prefer to take on families that do not do AP. IMO, real AP can only be followed by stay at home moms or families that hire nannies willing to follow this approach. How hard it should be for a child going from be worn most of the day by parents, falling sleep with parents every time, and not let them cio at all to group care where they have to be able to stay on their own, self soothe when going to sleep, and be able to wait until the provider is available and not run to the child after every whim.

Even I stay at home, I could only partially follow AP since I had to prepare my son to share mom time with others. I wore him even during daycare hours sometimes until about 1yo, but I prepared him to self soothe to sleep and play by-himself too before I re-opened. I also let him cio sometimes and taught him to wait.

On the other hand, it sometimes has to do with the child's personality. In June I took on a girl that was strongly AP (I don't follow AP with dck, only with my own, but l am closer to all of them when they start since I empathize with them on how scared they must be the first days). Well this girl adapted very well very fast. Even for nap time she got it in about a week.
