What would you tell a Pinoy mom who refuses to babywear for fear that her chid will grow up "sakang"?

I would say the truth. That "sakang or bowleggedness" is hereditary and has nothing to do with babywearing. Most people still lack knowledge on babywearing and sometimes the best way is to just ignore them if they judge you. Another route would be to invite them to join groups such as babywearing philippines.
