I can pretty much recognize which is which by my reaction to the situation. The more logical, the more likely it is not the child part. Or if I am especially impulsive, or emotionally reactive to a situation, then it more likely IS the child part. I assume I'm adult with child parts. Because I am obviously an adult, but I just have certain stuck points where things didn't go right and I didn't learn the right ways to cope with things that happened or get my basic child needs met, and I need to relearn them. At least I think? Lol.
