This theory is basically: Stick to a STRICT schedule; feed baby 4x a day, four hours apart, for 30 minutes each; two naps: one in the morning, one in the afternoon; put them to bed awake, leave the room. Go in if they are still crying after 3 mins, help them settle again, do it over again. Don't pick them up, don't feed them. She says it will take 3 days for new babies, and 7 for older babies and they will be sleeping 12 hours a night. I am not sure about feeding a baby (especially an infant) only 4x a day. It seems to me that if they are hungry, you should feed them, not make them wait. Also, the schedule seems super strict. I think a schedule is good for any body, but it should have a little wiggle room...especially while I am going to school. Maybe I just want the easy way out, but I guess anything you want takes a lot of work right? She also has a section about vacationing, sickness, and other circumstances and how to deal with them. I found that section very helpful. Despite all the negative things I just said, I think out of all the methods that I have read so far, this one seems like the one I roll with the best. We will see how Heather rolls. :)
