Welcome Janb!
This is a fantastic site, scroll through the previous posts and I'm sure they will help you along the way.
Penny Tassoni is a must for this course, I use her Child Development book, I have the 6-16years one as I have done up to 8years in the Level 2. If you haven't done the Level 2 you will need one that covers birth to 16.
I also have NVQ Level 3 Children's Care, Learning and Development- Penny Tassoni, Kath Bulman, Kate Beith. This is the text book we were told to get in our first lesson at college.
If you are stuck on anything and have already scrolled through and can't find what you need, post your question and I'm sure you will get help you need!
Good Luck!
