oh yea! They definitely need to have a lot of attention at first! I am giving it as much as it wants Still, once they are sentient, they can interact normally, I think, right? Yea, my tulpa, it wants different things than me. And it might get them! Hehehe
Attention and suspension of disbelief are mandatory. Once they are are able to interact with you on their own. They still may need to be "woken up" to act, or keep in the background and chipping in as they want. Depends on the Tulpa.
