I did not go to your blog as I am an emotional mess today. But my son is going to be 3 in January, and weaned a year ago. We had the same where I kept offering. I asked him if he was done and he said, yes, he was done. So we weaned. It was that easy. As far as stopping. But I still miss it. Even a year later.
So, enjoy the relationship you shared, rejoice in knowing you gave your daughter the best, and you will have the strength to move on with grace. Many hugs.
