i'd have thought it would make sense, really, and in a way i don't think it affects people who post on mn, iykwim?
we are all of us very interested in being the very best parents we can be, hence the fact that we post here looking for advice and tips rather than just not bothering and letting things take their course.
we see people on here asking how they can relate better to their children, how they can avoid losing their temper, how they can best nourish their children and which are the healthiest and tastiest recipes. we are all trying our backsides off.
But...i have a suspicion that of a general sample the people who managed to persevere with BFing will be those who are most committed to the welfare of their children. i hope i have expressed that very carefully indeed.
Because as a formula feeder i know that i am committed to the welfare of my child, and no amount of surveys or research will sway me in that belief.
(But, as a formula feeder i would have to say that there are some of my ffing sisterhood who maybe don't bother quite so much, or haven't been brought up to bother so much, or have been educated to bother so much, or have been fortunate enough to be in a position to bother so much. I am really, really, really trying to express myself carefully here... have been hurt plenty by bf/ff threads in the past and would hate to inflict similar on anyone here)
i see that the researchers say that even if we adjust the weighting for class, wealth, education etc there is still some benefit and do you know what? i can live with that, really i can. BFing is better for our babies, if we can do it, and those of us who struggled to do it and didn't manage, or those of us who opted not to do it just have to wear that fact.
whether the research was thorough enough, or the headline on the story accurately reflected the results, or whether the sample group was large enough or the study conducted over a long enough scale of time is pretty immaterial, really.
mental illness is a complicated thing, affected by countless variables. So this may be one of those variables... so what? there are other things we ffers can do in the meantime, such as being good parents and trying our arses off to take care of the variables that we can have some effect over. and as it happens, i truly believe that everyone on MN falls into that category of parents, ff and bfers alike.
