Adverse reactions for vaccines in older children - specifically DTaP, Hib, Prevnar 13, MMR

I have a 3 year old unvaxed daughter, that I am considering starting selective vaccination as I will be starting her in preschool next year.  

Our family (3yr old, 7 year old boy/girl twins, husband and I) is extremely vigilant with hand washing and all take Vitamins A,C,D,Cod liver oil, probiotics, and Jucie Plus daily.  But I am concerned about her contracting something nasty when she is around other kids daily.  Looking back at my twins' vaccination history makes me sick to my stomach - seeing what I "let" the doctors stick them with as preemies and during other illnesses - I hate that I was so trusting back then.  They received all vaccines  except their 4-6 yr old boosters.  Their worst reaction was my 1 yr old son to the MMR/Varicella vaccine (ongoing fever for 7+ days, rash, vomiting). But it's the long term side effects that scare me more -- he ended up starting to have intestinal bleeding between age 2 - 5, and then they found a juvenile polyp, for which he then had a polypectomy with added complications.  Looking back at him being given the MMR vaccine on the tail end of him being hospitalized for dehydration from a stomach virus was a really bad call by the pediatrician -- his intestines weren't healthy enough to handle that vaccine properly.

Anyway, for those of you who have waited until age 3 or 4 for vaccines - have you noticed less adverse reactions than previous children OR more reactions because their immune system is stronger and therefore overreacts?  Also, after titering my twins it is showing they do not have immunity to Tetanus or Pertussis (the Diptheria part worked).  Has anyone done the newer Tdap for 7 year olds?

I don't really have your experience, but I'll tell you what we did.  My twins were vaccinated on a delay schedule for their infant shots, but that ment we did most of what was required, just broken up into different months. At 16 months they had MMR, and then nothing until just a few days ago.  So they had about a 5 year break.  Little sister was given TDaP and polio vaccines as a baby, but not on schedule, and then she took about a two year break.

We just made it back to the doctor (I've got a thread on here about it) and decided on MMR.  It was the boys' second and her first time with this one.  They have had a low grade fever (99.0) when I've checked, but no one has acted strangely. I was very worried about a major reaction, but so far all is well. I do think that waiting until they are older helps, not hurts.

I was very clear when I went in that I wasn't looking to "catch up", that I was there for what was most pressing at the time. 

As for the TDaP repeat for your twins, I suspect I'd let it be, at least for awhile.
