Hey ladies,
So after reading the preparing your boobs for breastfeeding I thought I'd start a topic on increasing supply because to be honest this is my GREATEST fear/struggle. I wasn't able to pump more than an ounce (EVER) between both breasts, no matter how long I kept the pump on my boob for.
Part of my problem I think was that I never had her on me enough because of so many people visiting in the beginning and being afraid to kick people out. Not a mistake I will make again. Because I wasn't producing enough she wasn't gaining weight, or so I thought. We later found out she had severe heart burn and needed prescription zantac which eventually helped her. So anyway I ended up supplementing which further reduced my supply.
Is there anything any moms did before baby was born to help get supply going before baby was born? I may be jumping the gun because I am SOOO nervous about not being able to produce enough and I REALLY want to BF this time as long as possible, if possible. But if anyone has any suggestions, I'm open to them
Re: Breastfeeding - increasing supply BEFORE baby
With my oversupply my son had foremilk/hind milk imbalance and had horrible gas issues because of it
But it also meant being able to get a great freezer supply 
I think information is your best "preparation" for breastfeeding. I read every article on kellymom.com before I had my son and I swear it is the only reason I was able to start off so well. It was just nice to see the timeline they had set up on that website that explained about cluster feeding, and what dips in supply are normal, when the "usual" times of growth spurts are, etc.
Make sure that you're consuming enough calories through nourishing foods (now is not the time to try and lose the baby weight!) and LOTS of water. Rest when you can, and try not to stress, as that can negatively affect supply.
Eat oatmeal. Doesn't matter if it's plain, instant, loaded with toppings, or in baked goods--eating oatmeal will help.
Lots of skin to skin time! This will naturally increase the baby's nursing, and well as signal your body to make more milk. I've gotten a full let-down just from doing skin to skin without nursing before. That time is powerful--and messy!
Get support, whether it's LLL, a lactation consultant, a friend who has nursed successfully, or your mom. Make sure you have that support and knowledge from someone who has been there.
There are definitely other things that will boost milk supply (fenugreek, mother's milk teas, brewers' yeast, flaxseed oil, etc), but be cautious in using them during an early nursing relationship. The first month is when your body is adjusting to the needs of you LO, and excessively pumping or taking supplements will lead to an oversupply (which can lead to engorgement and mastitis).
Good luck, ladies!
Once your baby is here nurse as much as possible. Even baby just comfort sucking will help.
Make sure your eating plenty. Always have snacks at the ready.
Water! Water! Water! You've got to stay hydrated.
Nursing is very demanding in the beginning to ensure you've got a good milk supply.
If at all possible, avoid the pump for the first several weeks. A baby who nurses is more sufficient then a pump. Even if you think your baby isn't gaining weight. I know there are certain circumstances with this though, so I'd Def. Seek out a lactation consultant early on, even if you feel like you've got it down.
Don't get discouraged, and just keep pressing on. I got so discouraged because my son's pedi freaked me out saying he wasn't gaining weight good enough and I needed to supplement immediately! I'm so glad I didn't take his advice....I knew in my gut he was fine and at least he was gaining weight. ... Even if it was 'slow. '
With my second, my milk almost came in immediately. I did not pump at the hospital and nursed on demand. I pumped when I got home and had an impressive freezer stash in no time! I nursed him till he was 14 months. I was also home the second time around and did not have the stress of returning to a job I hated.
There is nothing you can do to prepare now except have a little faith that your body will remember. Best of luck to you!
