Well, I know some people say it isn't roleplaying or a role but I don't really understand what they mean by that. In psychology it is understood that people, everyone, has different roles that they present throughout the day. There is the role you present when you are at work, another when you are with your friends, or with your family etc. etc. I think this is just one more role that we play in our lives, just one that is very special to us.
Now, all these roles that we present in our day to day lives may be distinct, but they are a projection of our personality, something that is unique to each of us. A role is the part of us that we present at each moment of the day. In this sense we are always playing a role. When we are "roleplaying" we are just making a more conscious effort to present a specific or idealized role.
As I write that I think I realize why people might have a problem with the words role and roleplaying. I guess many people associate these words with acting or pretending to be something you're not. One thing I would say to that is that words can have more than one meaning. The other is that to a certain extent we ARE pretending to be something that we are not. The fact is that we are adults first, and being adult babies (or adult littles) is just one of many parts of our lives. Remember the saying that you can't be an adult baby without first being an adult.
ABs who live as babies 24/7 are extremely rare. ABs who wear diapers (and are not incontinent) are fairly rare but people actually live it as an actual lifestyle are almost nonexistent. Just about all of us have the regular, normal, day to day issues of adult life as everyone else in the world. We go to work, we pay our bills, take care of our adult responsibilities as well as adult hobbies and outside interests. Being an adult baby is only a part of our lives, even if it is our very favorite part, and part of having a well balanced life. If you are going to claim otherwise then that implies the alternative, that your life is out of balance. I think we all know that this is not true in most cases.
Look I understand that sometimes it feels more you are a little kid that is pretending to be an adult than the other way around. The fact is that most of us are quite capable of being responsible adults when we need to be or when we want to be. That is the difference between Adult Babies and people with arrested development. Language can be confusing when words have more than one meaning. I don't want to insult anyone, tell them what to do or who they really are. I am just suggesting that you be careful with the words you use and their multiple meanings, especially when interacting with vanillas who may be critical of us.
