first let me say that e.a.s.y. is totally worth it and you will be so glad you did it...
BUT for the first few days (ok, weeks) do NOT feel pressured to get everything right. seriously, just enjoy that precious time with your baby. it will be gone before you know it!!
i spent the first 3 months or so of my dd's life obsessing about her sleeping, eating, etc and was so angry, frustrated, stressed, etc when things didn't go "by the book". i wish more than anything that i could go back and just enjoy her sweet little self and not stress about anything.
we tried putting her on easy from day 1...no small feat..in fact, for us anyway it was impossible. she insisted on eating every 2 hours, would not sleep unless someone was holding her (except at night), and could not stay awake for any length of time. so what we decided to do (after many needless tears on my part) was to take e.a.s.y in steps. for the first month, i just worked on getting the feeds 2.5 hours apart. for the second month, we worked on the e-a-s order of events. then when she was about 8 weeks, we started sleep training.
so my best advice to you is by all means try e-a-s right off the bat if you want to. but if things don't go so well at first, take it in steps or try later. most importantly enjoy your baby no matter what. i once read that babies are like slow cooking stews rather than "on the brink of disaster" souffles...you have lots of time to correct your mistakes with them. of course the earlier you start the better and easier it will be, but don't stress if things don't go as planned right away.
like i said, we didn't really start the true "easy" plan until dd was over 2 months, but she did fine and is a great sleeper (usually!!).
congratulations and good luck. you will find lots of support here.
