dear colleague,
great that you are willing to try and realize you need help.
Is there no-one around that knows a bit about paediatrics at all?
I would certainly suggest reading all the posts in this forum (last 2 years).
Some of your questions will be answered in them. You will find a lot of references.
I can certainly advice to go to www.skillforaction.com and start reading there as well.
I wish you well.
Esther
