Got a job as a Peds. nurse.... need overview please!

Hello fellow Peds. nurses! I am a new RN grad. and just got a peds. job in an office. I really like it. I really do! I wanted to ask you all.... I took Peds. in school, but I am not really up to speed on the area of Peds. nursing. It was a while ago when I took Peds. Adult medicine I am on top of, but not the Peds.

Is there a good simple, yet explanatory book I could buy to read over in a few weeks that will give me a good general overview?? Someone mentioned earlier a book that I have seen the doc. reading and it looks 'medical' and quite in-depth. I need something simple and quick to get up to speed. Anyone know of a good Peds. book that will give me a good overview and get me up to speed? Like, in the first 6 months of life, the baby will be on BLANK formula and will exhibit the BLANK grasp and will show the following motor skills, etc. Also... immunization info. would be good too. The parents ask me a lot about immunizations and I really don't know much about this. I am just not versed enough on Peds. I am a newbie here! Help please!!

THANKS VERY MUCH!!!
