I just wanted to add that even the AAP says that solids are best started in the 4-8 month range. So 6 months is a guestimate, even for them. Waiting till 6 months is best (that's what LLL recommends), but some babies aren't ready till 8 months or even a bit longer.
Mommal was much more succinct, and I agree with all of the above! :rolleyes:
