You can find most of the information for BLW online. We love it! But, I do want to suggest the Hungry Monkey by Matthew Amster-Burton. It is not an instruction book or anything (although it does have recipes in it) but its a really fun read!
This book is HILARIOUS and has made me feel much better about not stressing the picky toddler stage. I have read it twice and I’m about to read it again. I can’t recommend it more highly.
