i have no problem with women breastfeeding in public. some women has mastered the art so that no one is even aware of what they're doing.
but for the diapers...eeewww....i had a women change her baby's diaper on the table in the restaurant where i work. i didn't notice it until i walked up to them with my all their food. imagine my horror when i saw the dirty diaper on the table and hearing the mom tell me to go ahead and put the food down.
