MovnMama: thank you so much for your post. I am in a similar situation as you. I also feel that many BFing mom's can be very judgmental and down-right hurtful in their comments and assumptions. It sounds like you are trying your hardest and doing the best you can be.
I also feel saddened my little one is not taking to the breast. I'm not sure if it is a nursing strike or CLW (most likely not), but in any case, he hasn't taken to the breast in almost a month even with offering. He prefers the bottle and formula, most likely b/c he is impatient and it is faster and easier for him to eat. I also had to go back to work a month ago, which has made BFing even more challenging.
I miss the bonding time, and I've struggled SO hard with producing enough milk from day one, have seen 5 lactation consultants, pumped, continue to take EVERY alternative herb for increased lactation, and I still have a very low supply. I try not to feel inadequate as a mother. It is difficult enough not to be hard on oneself, let alone having other mother's judging your life situation.
Know that you are doing the very best you can at this time for your child, and that you are not alone in this situation.
