Congratulations on your baby!
I agree with the above poster - think it depends on the baby and you.
My friend did EASY and found it fitted her baby's natural rhythms so it gave their day a useful structure (until he turned six months old and wanted to crawl and then cruise, then he wasn't interested in the same pattern so she had to adapt it). So she loved EASY and found it really helped her stop over-tiredness and so on.
For me, my DS1 was so far from fitting the EASY pattern that our whole lives would have been spent squashing him into something that didn't fit. He found sleeping so hard that he rarely napped at all (still hates sleeping at three!). I used to despair because I couldn't see how EASY would ever work for us if I wanted to get out and have a life.
Funnily enough, my DS2 would be a perfect candidate for EASY as that fits his natural patterns, but I find any real routine is pretty much impossible as he simply has to follow whatever DS1 is doing, so has to catch naps on-the-go and so on!
So why not give the principles of EASY a try and see if they work at all? If not, maybe it isn't for you and that is okay too. Having had two babies with totally different rhythms, patterns and personalities, I think it's most important just to find what works for both the baby and you, whether that is a routine or just following their signals for when they are tired/hungry (if you can understand them, which is also hit and miss sometimes!).
