The thing is, it's really all supply and demand, As far as the advice you are getting and how it differs, it may depend on where people are in their commitment to see that your child gets the breastmilk as well as the bonding that nursing creates.
You've talked about bringing the baby to the breast every two hours. How often are you supplementing and how much? Is it topping off or separate feedings? You keep talking about when you go back to work. Are you only committed to feeding the baby breastmilk until then or are you committed to pumping while at work and nursing to reconnect with your child when you get home at night?
I can see you are doubting your self by the title of this thread. I am sorry that you are feeling that way. I really am. However, there really is no reason to think you can not get the baby all the way to the breast. You were made to breastfeed. Plain and simple. You make milk. And will make enough milk for your child if you get your child to your breast as often as she needs to eat. No matter what you have heard to the contrary. No matter who tells you it's not true. Even if the person giving you bad advice is your baby's doctor. The fact is, as long as your body get the right number of signals AND the baby is latching correctly, you will be able to do it. I wonder if the situation at the two week point had more to do with the baby not latching well enough to transfer milk than actual supply problems?
Is your breastfeeding support group really helping to support you? Or is it a bunch of women who aren't really succeeding being told it's normal or OK? Because if you aren't being given the solid resolve you think you need to stick with it, I HIGHLY recommend you contact your local LLL leader and find your way to a LLL meeting. I find that the energy in those meeting is often very different than the "support" you find at a meeting run by the hospital or other places. You will find the energy you find coursing through these boards IRL people who you can see and touch.
At any rate I KNOW that you can do this. I understand that it's hard to have faith and believe. Especially when you have a child that is frustrated at the breast. Begin counting diapers. And lose the supplements. It's the only way. I hear that you have tried it already. That doesn't mean it can't or won't work for you and your child. It means you dig deep and you commit to the fact that it means all day on the couch. It means some tears perhaps. Because it's much harder to get all your milk from the breast than a bottle. But anything worth having is worth working for. I can tell you that if you do the work, you will never be sorry. You will never look back on this time and think "what a waste of time. I should have never spent all that time fighting to get her EBF." The ability to feed our young is a fundamental piece of who we are. Much of the sadness you are experiencing at this point is tied to that. On your deepest and most primal level no matter what someone in a white coat is telling you or other mothers that have thrown in the towel, your instincts are telling you something. Listen to your instincts Mama. You were made to do this. Stay focused. You CAN DO IT.
Shelly said it all, But i want to add that I've been EXACTLY where you are, we supplemented from 2 weeks and it took a good bit of determination and alot of effort but we stopped the supplements and you can too mama
