feeder turned formula feeder, a little saddened by the verbal wars?

from all the feeding mothers i know they frowned upon me feeding my baby formula they would go on and on about how i was letting my baby down. but i fed her for 10 weeks and she wasnt gaining much weight turns out i didnt have much milk and i was so upset when i couldnt feed her myself but what was best for her was to have formula. my feeding friends not encouraging me to be a good mother but trying to push their beliefs on me. being a good mother isn't about feeding its about looking after your baby making sure they are well cared for.
