I'd have to agree that AB and DL's, although sharing similar traits, are quite different. I go into moments which are either purely AB, or purely DL. For each, the emotions and needs vary. And yes I also agree that there are different variations of AB's as well. I consider myself an AB, however I'm not interested in crawling, bibs, baby talk etc. I have my diapers, a pacifier, bottle, and love to cuddle. And in 'DL mode' I have no desire for anything besides diapers
