My first piece of advice is to take a deep breath and relax....I know that timetable can be a bit confusing, but you can get this figured out and do what's best for you and your lo!
That schedule on pg 230 has been the topic of a lot of confusion and many discussions on this forum. We even talked to Melinda Blau about it. No one is certain what exactly is supposed to be right, but here is what we think the idea is: to extend awake times working on one awake time every three days. For instance, after the first three days observation, you would work on extending your lo's first awake time by 15 minutes. Then, after that is working, you would extend the second awake time. Does that help or make any sense?
Don't forget that you know your baby best, and that Tracy suggests that EASY be a guideline and not a strict schedule. She also posted those (and every other schedule in the book) as a guideline.
YOU CAN DO THIS! Just be patient and know everything won't be perfect, but things will fall in to place.
