Good night, younger one is two months old, we gave vaccinations at birth and in the month, but I don't know what to do after that, all acquaintances refused vaccinations, and even those who didn't ask also, especially for kids, how do you feel about vaccinations? Older one did everything, he is 2.8 years old, still doesn't talk.
