I have four children ranging in age from 5 to 12. When our oldest was born, the conventional wisdom said to have all vaccinations completed by 18 months. By the time child #4 came along, it was a 12 month sprint.
Depending upon your views and research, do not hesitate to question your gp/pediatrician re: vaccinations and the scheduling thereof.
I put my foot down when they wanted to give multiple vaccinations at one time. By this I mean that the doctors wanted to give more than one kind of shot to the child (some of the vaccines are "combination" vaccines for more than one disease and are delivered in one shot). The doctors were proposing to deliver two or three of these combos in one visit.
I protested on the grounds that if the child had a reaction to the shots, how was I to tell to what the child reacted? The doctors recognized a tough old broad when they saw one and the old schedule of a completed course of vaccinations by 18 months was re-instituted.
It drove them nuts in terms of their special little charts, but I refused to back down.
My mother told me the same thing. Even 30 years ago, when many people just vaccinated their kids and didn't think about the consequences, she made them spread everything out. She wouldn't even let them give us the MMR. She wanted a separate shot for each.
