I highly doubt that's the case. In order for that to be true, one must assume that parents who do not breastfeed are purposefully doing the opposite of what many resear...
If only around 1% of mothers cant breastfeed for medical reasons then the other 99% are choosing not to follow the guidelines.The 1% are not going to effect the results too much.
This is nonsense and doesn't hold up in real life. Though the statistic you are referencing may be true, 1% of women cannot physically breastfeed, this does NOT mean that the other 99% CHOOSE not to.
Many women cannot breastfeed because they are not supported enough and because they are misinformed by poorly trained medical professionals and already believe they have 'failed' at breastfeeding before they really have. To insinuate that those people CHOOSE to formula feed is insulting to them and not at all helpful.
