[Toy Story] When could we estimate the first ever living toy came to be and what could it have been?

I'll start by saying I have no concrete knowledge of the history of children's toys. A cursory google search reveals that dolls and teddy bears date back in our various cultures over thousands of years, but I'm wondering if something more basic and primitive could have been the first ever living toy?

The rules for which toys are alive are quite ambiguous. In Andy's room, the only toys that are alive are the ones with faces. In Sid's room, though, there are several mutant toys that don't have faces (like the fishing rod with legs) that *are* alive. One possible explanation is that a toy gains life when a child thinks of it as alive. So in one child's hands, a dump truck toy would be a machine and not alive, but another child could imbue that toy with life by including it as a speaking character in a tea party. 

By that logic, the first toy to be alive would be the first doll that a child played with or the first stick a child picked up and pretended was sentient.
