I worry that moms who have had experiences like you did will no longer feel welcome in traditional clinic settings.  A hodge podge of stay at home parents dabbling in medicine (oils, plexus, thrive), chiropractors and internet groups are taking the place of doctors when parents feel judged for parenting decisions that have no risk to a baby.    I DO follow the standard CDC vaccine schedule, do not advocate for co-sleeping due to risk for suffocation under 6 months but DO support breastfeeding until mother and baby are ready to wean. We should be able to have open discussions with patients that are evidenced based without passing judgement for things that are culturally based.  

For example there is some debate as to whether prolonged breast feeding leads to tooth decay but not in every situation.  Frequent overnight feeds, pacifying on the breast overnight and not cleaning the teeth afterward do seem to increase the risk. Just the simple fact of breast feeding a 16 month old does NOT lead to increased dental caries though.  Doctors sometimes remember patients that did have dental caries from a combination of factors that included prolonged feeding (breast or bottle really) but don’t realize the other factors that were at play and blame just the breast feeding act, which is an oversimplification and wrong.  Your doctors reason seemed to be just culturally based not medically based.  Over eager parents sometimes encourage breast feeding without caution for those other factors but don’t see the 2 years old with dental abscess and loss of all front teeth.  There is a middle ground for sure and discussion that can take place without shaming.  Sorry for the length.  Cheers.
