I spread vaccines out so that my 14 month old son is not getting so many at one time. I also have read ingredients and I carefully choose which vaccines he will get together. So far my ped has been pretty good about it. We decided not to do the rotavirus vaccine and we are waiting until my son is at least 2 to do the MMR. While my ped thinks we are waitin a little while on the chicken pox vaccine, we are seriously consider skipping this one too. However, it is required that he get it in order to go to school in IL where we live. Not sure how we will handle that. W did do the HepB series, but I think I would skip that with my next child.
The vaccine book has been a useful resource for us.
