I actually gave this a lot of thought and research.
But please note each child is unique and where they attend day care will dictate your personal needs and schedule.
But here's my journey and thoughts. I initially began researching what the vaccines were/ side effect / importance. I did this by talking with our ped, lots of reading and suprisingly even Dr. Oz promotes extending vaccines (he did this for all his childeren).
From what I can tell and have read, I do not think a little person should have 3 shots of anything. Its a major overload to thier systems - and many combo shots have adverse reactions - where as if they had given the child one to two shots at a time the fevers/ heart failures/nerve damage etc... could have been avoided.
They have mixes of multiple vaccines in one shot, so I try to make sure Liam (my lil man) in this case only gets two shots at a time or one when it comes to the big ones like MMR and what not. Also I have put off getting shots like the flu, chicken pocks, etc. ( I know this sounds counter intuitive but there are some great studies out there supporting this decision and the vulnerablity of thier systems when introduced to live flu - wow - its not good) While it is a good idea for the second to keep pregnant women healthy, I think if it is a normal illness that they will get over, strengthen thier immune system and it will not hurt them then no shot for me.
Also depending on your thoughts, I am not sure why babies need Hep B (two shots before they are 1). No good information for promoting the shot at birth and lots against the shot. Liam is not going to be in a nursing program. so he should not be dealing with other peoples blood and what not. again a toss up, not a biggy but still.
I think the most important part is to talk to the Ped about what our babies will really need - as mine will be in a home daycare setting with only one to two other kiddos his exposure is limited. But we all know that kids can be super carriers. so again you need to really talk this out with a PED.
My goal is to stretch out all his shots well past him being two. I found a schedule that gets him his shots by the time he is in school but spaces them out over 4 years vs 2.
here is a good ext version. note there are only two shots per time. This is not always feasible as they mix some shots together but it should help with the timing, and I think that is the most important part.
2 months- DTaP, Rotavirus
3 months- Pc, HIB
4 months- DTap, Rotavirus
5 months- Pc, HIB
6 months- DTap, Rotavirus
7 months- Pc, HIB
9 months- Polio, Flu (2 doses)
12 months- Mumps, Polio
15 months- Pc, HIB
18 months- DTaP, chickenpox
2 years- Rubella, Polio
2 years, 6 months- Hep B, Hep A
3 years- Hep B, Measles, Flu
3 years, 6 months- Hep B, Hep A
4 years- DTaP, Polio, Flu
5 years- MMR, Flu
6 years- Chickenpox
12 years- Tdap, HPV
12 years, 2 months- HPV
13 years- HPV, Meningococcal
again this is only a suggestion and I know by working with my PED that this will work for Liam- it may not be whats best for you little one.
