I realize it every time it comes up, and I'm fine with it. The juxtaposition of adult vs. childish or infantile is what makes this work for me, so I don't have any desire to literally be a child or baby. Doing it once was hard enough.
Although that might not be the most common position for an AB. it fits with reality and I think it's not so bad for other ABs if they'd just accentuate the positives. Outside of brain damage, there's no way to really lose the experience we've accumulated. It can be de-emphasized for a period of time but we are what we are. I think it's more positive to see that using that experience allows us to know what we really want out of being ABs and lets us form complex relationships and communicate those desires to others. It involves effort. I just think that looking forward rather than backwards in our development and our relationships will ultimately be more satisfying and productive.
