We read everything Emily Jenkins writes (for kids; she also writes for adults, but I haven't read all of that. Yet). What Happens on Wednesdays (illustrated by Lauren Castillo; Farrar, Straus, and Giroux, 2007) was of particular interest to Milly, who is starting to pay more careful attention to the days of the week and the routines that correspond to each one. WHoH is as much about the preschool-aged narrator's (urban) neighborhood as it is about what she does there, and Lauren Castillo's mixed-media illustrations of Brooklyn in winter are warm with just the right amount of detail.
Jenkins writes (on her amazon.com blog) that "[her] hope is that readers and families will map their neighborhoods and write down their schedules, focusing not only on the events and locations that are important to the adults for navigation and structure, but on the things that matter to the children as individuals." And that's exactly what the kids started working on, without any prompting from me, as soon as we finished this book.
