Visitor Vaccinations

Amy
So my doctor told me to make sure that the visitors in my baby's first couple months of life all have updated TDAP and flu shots. I told my family about it and got a lot of flack. They don't seem to understand what a big deal whooping cough can be to a newborn. I feel strange insisting  my parents get the update, but they are really fighting me. They say my grandparents won't come if I require this. What have you all heard about vaccinations or family and yourself?
