Mycenaean children's artifacts are rare, but they have been found, as attested by these miniature feeding bottles.
In one excavation, a doll's head was found buried with a girl. At first, the archaeologists assumed the head belonged to a cult figure placed there to protect the child in the grave, but then someone pointed out the little holes where the head would have been attached to a cloth body. No religious artifact this, but simply a child's doll, accompanying her mistress into eternity.
