I think a great place to start is Bright Futures from the AAP. Check out the website brightfutures.aap.org. The "Guidelines and Pocket Guide" section is useful. The guidelines provide detailed information categorized by age/stage or by theme. The Pocket Guide is more concise and highlights the important things that should be addressed at each visit.
All of these resources can be downloaded as a PDF. Your program may also give you a physical copy of the Pocket Guide when you start (mine did).
