I understand your problem with immunizations. Since the 1980s, the medical community has gone from giving 8 shots before the age of three to 32 shots before 2 years old. I don't think our kids are any healthier, and in fact, think most are sicker.
I have a one year old, and we have practiced delayed immunization. My concern, besides the mercury, is the nimber and schedule that immunizations are given. We have waited for her to be a year old. After doing research, I feel that too many immunizations are given at one time. We are eliminating some shots, like the DTP, and will given her only one shot at a time, so we can monitor the effects, and any reactions.
I also won't be giving her chicken pox- when you have it as a child, you have life long immunity, but with the vaccaination, you have keep getting the shots. There have been recent cases of adults getting chick pox, and they are just not as able to fight off the disease.
My ped will not give just one shot at a time, so I have to go to the health department. That said, if your child is only 6 months old, you still should have seen your ped more than you have.
Also, my husband is a stay at home dad, and my child is not in daycare. If she was, I would catch her up- still by doing 1 shot every two weeks.
Finally- sorry to be long winded- you do not have to have your child vaccinated. This is because even the companies that provide vaccinations, and law makers realize there is a small part of the popular that will have severe reactions to immunizations. If you were required by law to have your child vaccinated, and the child died, you would have a great lawsuit on your hands. The best way to circumvent the vaccination issue with your ped is to sign the wavier saying you object for religious reasons.
