Hi, A.! Congratulations on your new baby boy and all the joy he brings!
I would highly recommend a book called Super Baby Food; I'm sorry I can't remember the author's name...I'll try to look it up for you and send it on, but I think the last name starts with a Y. Anyway, it sounds as though you are organic-focused like I am, so I think you would really like this book. It helped me so much when I was starting my daughter on solid foods, and I plan to use it with my 5-month old son, too (he'll be starting solids pretty soon!). The book addresses when to start new foods, how to make them yourself (if you want to), why foods are introduced in the order they are, what benefits they have for baby, etc. It also gives great recipe ideas for toddler foods later on, and the whole book centers around healthy, fresh foods--I always bought organic, too!
Enjoy--it's awfully fun!
S.
