Or it could mean she is expressing an inate drive to take care of a young infant, and such a toy is a good teaching tool.
Come to think of it, in our house, I don't think any baby doll has a bottle anyway. My own babies never had bottles, I exclusively breastfed, so their natural inclination with a baby doll has never been to shove a bottle in its mouth. They've used little bowls and spoons to feed the dolls, but never bottles. I've seen my daughter hold a baby doll tight to her before but never thought anything of it. She knows what "boobies" are and that she got her milk from mine when she was smaller. Heck, I really don't see anything "creepy" about such a doll at all. One with a bottle would be the "unnatural" one.
