I think what you describe is very common. I would not call it child-like necessarily, adults also do all kinds of provocative/destructive things to get attention and communication, especially if reliable, positive feedback is not available. I just think that we first develop this early in childhood, then learn more productive and mature ways, but it never really disappears, probably just gets a bit more sophisticated and controlled.

The thing with Ts (or even just between adults in general) though is that this type of attention seeking can become very transparent very soon. Then they will stop feeding it which, IMO, is not a bad thing given that there is no way a T could consistently satisfy these needs. What I like to do when I find myself seeking attention in ways and in contexts where I could not realistically get it is to play it forward in my head and ask what exactly I imagine or wish to get out of it. What type of response, reaction, reinforcement. Would it truly help or be satisfying? I also do not think that impulses like that necessarily reflect attachment. Can be part of it, but it can also be just a desire to get instant gratification in whatever form we can get it. A good sign for the latter, for me, is how this type of attention seeking is not specific to a person - if I don't get it from one, I would be inclined to try with someone else, etc. So, for me, it is usually intrapersonal rather than interpersonal. A bit like OCD, when the urges and compulsion is a reaction to momentarily alleviate intense bouts of anxiety.

So maybe that's also a question to ask: is it an intrapersonal or interpersonal need? I think sometimes it is not easy to answer it.
