6 months is the new standard.....that said I started veggies first (6 months) then fruits and didnt introduce any grains until 8 months. Grains really are not needed at that young age, they just act as a easy food for young babies. My Dr said if i wanted to do grains at 4 months I could, she would wait till 6 though, if I wanted to start with a veggie or fruit first then I had to wait till 6 months. I follow the Dr Sears guideline a little more, which is a delay in grains and not making grains a large portion of the diet.
