I know that not all breast feeding moms are "Nazis" about it, but it does seem to be the prevalent attitude. I know quite a bit about attachment theory in the psychological literature, and the "attachment parenting" thing is somewhat of a perverted version of what attachment theory really is. I doubt Bowlby and Ainsworth meant that parents had to sleep with their kids until they were 3 or 4 years old. My cousin's wife did this and it just caused a huge wedge in the family.
I know that breast milk is nutritionally superior; it still didn't make me want to nurse. Soy formula worked well and they both switched to regular milk at one year, when they started using a cup.
Oh yes, and my kids were on "schedules," too.
It's all a choice and it's good that everyone can give Limewave advice. But, even after almost 27 years, I can still feel the superiority vibes that were thrown my way.
