Vaccinations and in laws 😑

My sister in law did not vaccinate her 3 kids and my mom who is a pediatric nurse said I should keep my baby away from them till she was old enough to have her vaccinations. Now I just found out my husband was never vaccinated either 🤦🏻‍♀️ anything I can find online says that unless there’s an outbreak or something it should be fine. This is my first baby and I never knew that vaccines were such a question honestly, so I’m very confused on what to do. What would you ladies do???
