it's not about the way they 'fed' their doll as such but getting kids in the mindset that seeing dolls with bottles is the 'norm' of feeding infants. A lot of predjudices we have against anything are firstly formed by what our parents think and we have to make our own judgements on it later on, and if a child was in a house that frowned upon the breast as being the premium infant feeding method and that bottles were the norm and then that idea was reinforced by what they saw outside of the home, then naturally you could go so far as to make the assumption that the person would be skewed towards thinking that the other is a more acceptable form and if it is a woman then she has to overcome that to be able to want to BF her own child. Do you see the point I am trying to make? It's not the childhood alone that can form a person's idea's on something but their whole life experience of it.
