Think of all the encouragement and inspiration you can give to other women who are succumbing to "the pressure"!
Read your post again. Look how far you've come!
I remember reading something that Dr Sears said about it never being too late to practice Attachment Parenting. I can hear how remorseful you feel and I pray
that God will help clear you of those feelings of guilt. Because He wants you to move on. Here is a verse to help you in Isaiah 43:18,19 "Forget the former things; do not dwell on the past. See, I am doing a new thing! Now it springs up; do you not perceive it?"
You did the best you could at the time w/the information you had. That's what we all do. You are a new person now... a new mommy and all your children will benefit greatly for it. It is certainly not too late!
Celebrations to you!

p.s. if your son wants to try nursing again, I don't think there is anything wrong with it whatsoever. He may not remember how to nurse, but I think he will very much appreciate you allowing him to try.
