Hi jennf!
OK congrats on your new baby first!! Well i started with EASY since day 1, but i din't follow a schedule per se, for at least a month, what i did was follow the order of things, for example: i never let DS eat to sleep, allways made sure and waked him if he got asleep during a feeding, you'll say "how do you wake a JUST fed and Sleepy newborn) well, i changed his diaper, and that alone counted as activity time, then i left him to sleep again, i never fed him if only an hour had past after his last fed, and at nights i kept to no lights or very dimm lights, and i didn't talked to him at night either, never rocked him to sleep, allways slept on his crib. And after a month or so he accually started to get hungry every 2 1/2 or 3 hours, so that's when i started the schedule of feeding every 3hrs, and when i also started waking him from his naps to feed. And by that time i already new his sleepy cues, so i got him to his naps and everything. The pat-shush method does work, but there were times when i had to pat-shushed hi for at least 45 min, but do try to keep to it, because now my DS doesn't need it anymore, and he can sleep only by placing him in his crib. We are currently on a 4hr EASY, and he naps really well (2hrs or so) and he sleeps pretty good at night too (doesn't need feeding at night anymore).
Well what i'm trying to tell you, is that EASY really works, it can be hard... REALLY HARD at firts, but its totally worth it!!!
Good luck and let me know how thing s work out!!!
