Am I the only one?

Who thinks that starting a 3-4 month old on solids is good idea? I've read so many "baby blogs" where mom's are starting their babies already on rice cereal, bananas, etc. I'm pretty sure I'm not the only one who has read the recommendation for the second half of the first year of life. Meaning after 6 months not necessarily starting at 6 months and definitely not 4. I plan on delaying solids a bit because I've done a lot of research on how it's better for the digestive system, and helps prevent allergies. I'm sure our Ped. won't have a problem with that since she is pretty crunchy. :) Now if I could just get my vaccine research done. Ugh.... I still don't have any of the books yet and I really need to get things sorted out before her 4 month appointment. Emerson hasn't had any vaccines at our request. Even the hospital asked me a good 5 times if I wanted her to have the HepB shot. I haven't had the least bit of worry about it considering I exclusively breastfeed giving her the best immune system possible. My gut is to still delay longer based off research on how all the chemicals can effect developing children's brains under a year. I'm not as concerned with autism since the basis for that argument is mostly based on mercury which isn't in vaccines anymore. But, I know a lot of people link it to the MMR combination shot (Measles-Mumps-Rubella) which administers live viruses. Although I've heard they will be bringing back the separate shots in 2011. Decisions, decisions.
