I’m new to scrapbooking and want to create a nice baby scrapbook. I already have an A3 book to fill but I want help with layouts, materials etc. A baby centered book is not necessary but if anyone could recommend a beginners book, and maybe a book that has some easy to follow ideas for layouts I would be very grateful 
Scrapbooking can be intimidating when you are just starting out, but it doesn’t have to be. There are a few books that would be a great help to beginning scrapbookers.
A few of my favorites are "The Big Picture" by Stacy Julian, "Creative Sketches" by Becky Higgins, and "Scrapbook Page Maps" by Becky Fleck. They are not specific to baby scrapbooking and are wonderful for jumpstarting your scrapbook pages on any theme, because once you start you won’t want to stop!
I also have a site devoted to scrapbooking with many areas related to beginners. You are welcome to check it out.
Good luck to you, and congratulations on the new baby!
