I have 2 daughters and with my first one I tried some of the Babywise techniques. With my second daughter, we have instead totally gone by her lead. This approach has led to so much more joy, has helped me to relax and be in tune to her needs rather than a clock. With Babywise I felt so pressured to look at a clock, confused what to do in between feedings if she seemed hungry, and tense about getting it all right (I realize this may be my personality type). Instead of using my intuition to connect with her, I used the "authority" of the book.
Now, as I said, with my second daughter we are so much more relaxed and enjoying each other as I seek to use her cues to guide our feeding times. This helps me to really connect with her more.
I share all this b/c I've seen a lot of my friends get very focused on the Babywise approach and lose a lot of the joy in feeding and nurturing their babies (just like I did).
I know this is not what you asked for, but I just wanted to ask you if this approach is working for you as far as establishing a real peace between you and your sweet little boy?
