Did you gradually wean your son or did he stop cold turkey?
I had my son down to nursing twice a day when he decided he was done (13 months old). This really helped my milk to dry up. I did pull out my pump a couple times when I felt engorged but didn't get much milk. After a couple of days I started to feel normal again.
I did feel sad for about two weeks. It's definitely an adjustment. We had many times during the day when we would sit and cuddle which seemed to help both of us.
I just had to start thinking of it as a new phase of his life was beginning. He was moving on to bigger and better things! :)
