I don't usually do this, but I stumbled upon a really top notch article yesterday on thestir.com. It is written by a mom who is doing baby-led solids with her third child. To sum up: baby-led solids is a natural, commonsense approach to introducing your baby to solid foods. There is also a nice bit of history of purees and formulas in there.
This article would be a great thing for you newbies to email to skeptical family members (along with sending them to my blog, of course!).
