No, I'm not suggesting that. They do. Have a look at the WHO study: http://whqlibdoc.who.int/publications/2007/9789241595230_eng.pdf http://whqlibdoc.who.int/

For example: "Even within the same social group, mothers who breastfeed are likely to be more health-conscious than those who do not breastfeed. This may also lead them to promote other healthy habits among their children, including prevention of overweight, promotion of physical exercise and intellectual stimulation. This may be particularly true in high-income populations. Because these maternal attributes are difficult to measure, it is not possible to include them in the analyses as confounding factors. Nevertheless, this possibility should be taken into account when interpreting the study’s results." I'm not resisting studies - I'm reading them, rather than relying upon misinformation from other sources.
