Giving Up Breastfeeding

On Sunday, I was a friend's place for a gathering. She also had a baby who was one week older than Soph but was soon moving to San Diego. Since I won't be seeing them for a while, we took the one hour drive there to meet up and say our goodbyes.
Somehow we were on the topic of breastfeeding and she told me how her baby had problems latching on but she visited a great lactation consultant who gave her baby therapy and improved things a lot. I told her I always had to supplement on formula because of my
physical issues. She offered me peanuts and asked me to go to her lactation consultant, the best in the bay area. I declined and tried to explain my situation. But she found it hard to believe how any woman cannot produce enough milk. It's true that some women have a low supply because of mishandling breastfeeding. But there is the also 5% of us who just cannot. She tried to make me feel guilty by saying "Well, mom's milk is the best after all." Ya, and why shouldn't I know that. I didn't really want to explain further.
Deep down, I know that I have been trying my best for the past four and a half months - eating all the herbs and food that boost milk supply, pumping pumping pumping. I still wake up in the middle of the night to pump, even though most moms have begun to get more rest as their babies start to sleep through the night. I used the SNS in a bid to make Soph nurse a bit longer. I think I have tried all the methods, some of which I doubt she even knew.
Two weeks ago, I have started to wean off breastfeeding. I didn't want to. I enjoy the closeness and bonding even though I had all the contraptions to make it work. However she was taking as long as an hour or sometimes more to feed even at four months. Sometimes we spent the hour wrestling to make her feed and she would refuse and cry and kept swatting me. I decided that this time should be better spent playing, learning new skills or taking a nap instead of wrestling with her to feed. After all she would be going to daycare in a month's time, and she should start getting used to the bottle. Now Soph is pretty proficient with the bottle, and she gets more play time and nap time which makes more sense to me. But giving up breastfeeding doesn't mean giving up offering breast milk. I will still pump eight times a day and squeeze out what I've got!
