This is such a controversial subject these days...and I must say I haven't done loads of research except for reading a book or two....I know that when we took Josiah in for one of his first check-ups I felt so much pressure to vaccinate him right there on the spot...otherwise I was a bad mother. So I yielded...and they gave my wee baby 5 shots in one day! I felt so apologetic and wished I had come in armed with some sort of conviction regarding the matter. 
Now?...well...let's just say that I don't want to blindly accept every piece of advice that medical doctors give me...Hence the books on my shelf... "How to Raise a Healthy Child in Spite of Your Doctor" (outdated, but a refreshing perspective)..."Smart Medicine for a Healthier Child" (thanks, Christa)..."We Don't Die, We Kill Ourselves"...Oh, wait...that's not directly related to child rearing....Sorry...
Just to throw in a clause here....I'm not anti-vaccination...well, at least not every single one.... =)...But I'm still thinking through this issue, and certainly do believe that there should be an alternative schedule...certainly it is not necessary to give an infant five doses in one sitting...the same amount that would be dispensed to a 5 year old!??
So, please be patient with my "trying to think outside the cultural norm box"...and don't demand that I have this all figured out....(because if you would have asked me two and a half years ago, I would have been completely anti-vaccination!).
Aren't we as mothers responsible and entitled to evolve and even change our perspectives as we season?
ANYWAY...
 Here's some food for thought....An interesting article I read through another blogger's site.
