HI
EASY is a component of Babywhispering - and babywhispering is something that you can start any time with your child as it will help you understand a lot of his behaviour and needs by using a lot of observation and BW techniques. the EASY part is the routine which is based on E (eating) followed by A (activity = awake time/playing etc) then S (sleep/naps) and the while lo sleeps is Y (you time) although the order is important in the early months it does evolve into a lot of different variations after 6 mo when solids and BF/FF are fit into a day so eating most likely happens twice in each cycle with activity on and off.
i recommend you read 1 of the BW books. there is the original BW book which really explains the philosophy and techniques (Secrets of thye Baby Whisperer), the toddler book (which amazingly really would be a good place for you to look as this really refers to the next phase you are entering) and then there is the latest which is ther baby Whisperer solves all yor problems which is a trouble shooting book to answer questions for implementing EASY and issues that crop up or habits you might need to break HTH
