my son was early and I had to pump the first 6 weeks to even have a milk supply and I fought with that the entire time I breastfed. I did breastfeed until he was a year old. What I learned is breastfeeding is as much an emotional thing as a physical thing. When I pumped, I would have to make an effort to relax and think of my baby. I would have to close my eyes and picture him, think about actually breastfeeding him. That helped more than anything. I had to pump more often than I actually breastfed. Nothing, is a effective as feeding your baby, so I increased my pumping frequency to compensate some. Which at work is hard, but I found 10-15 minutes every 3 hours much better than 30 min every 4-5. I also think when you hormones start cycling again your milk produciton changes with that. I would notice a big drop off in production right before a period, so I would step up the production tactics to get me through that time. Then when it was over I would have more than enought milk again. The other most important thing I can tell you, there is nothing wrong with supplementing with formula. I believe babies don't get confused about nipples. The get lazy, breastfeeding is harder work than bottle feeding. The best advice the breastfeeding consultant in the NICU gave me about that was I am the parent and this is my first tough love parenting task. She said if your child wants to play in the street,you tell them no, if they whine and cry you don't give in, because that is what is best for the child. The same for breastfeeding. What every you give them to eat, they will eat if they are hungry enough. I had a very hard transition when my son came home from the NICU because I had only breastfed him once a day and he had bottles the rest of the time. He wanted food quick and easy, but it only took a few days and he could go back and forth between a bottle and the breast like a pro. I would never trade that one hard week for the experience of getting to breastfeed him for a year.
I don't know where the idea that you have to do either all breastfeeding or all bottlefeeding came from but in today's busy life of working moms, I think somewhere in the middle is a must. Don't feel like you are a failure at breastfeeding if you child is hungry and you give him a bottle. If you only breastfeed once a day then you and your baby will cherise that once a day. Your baby will still get the important things he needs from you if you breastfeed any amount. So try not to stress, relax, enjoy your pregnancy and wait to see what works best for you and your child
