Non-vaccinated children around newborns

Rhianna1981

I am not sure if this is the best place to post this question, so if you have a suggestion about where else to post this, please let me know.

Anyway, I have a friend who has a three-year-old. This friend of mine does not believe in vaccinations. She and I frequently get together, and I anticipate continuing to see one another after my baby is born; however, now I am concerned about exposing my child to her child if her child is unvaccinated. I certainly plan on vaccinating my baby, but I know that the vaccines are spread out, so the baby won't have immunity for a while.

Is there any risk in exposing my child to something, if he/she is around a non-vaccinated child. Can the non-vax'd child expose my not-yet-vax'd child to something, even if the non-vax'd child does not show symptoms?
