For development:What's Going on in There?
--summarizing neuroscience research in (fairly) everyday language to explain what's going on in your baby's head. Super interesting if you like that sort of thing.The Wonder Weeks
--it's got a terrible title but it's sort of a bible for me (note: I have it in another language and haven't seen the english version, but I'm guessing it must be basically the same thing...Also, there are some non-AP quotes from parents in it. This doesn't diminish the value the book for me, since it's nothing the authors advocate)
For eating:Baby-led weaning
totally random:Mothers and Others
--by a sociobiologist, about the prevalence of cooperative parenting and its importance in human evolution.
