I agree with the other poster - definitely talk with your OB. I'm glad you are willing to give it a try. I had a heck of a time feeding my first in the beginning, too. He actually had motor issues, which we didn't know until he was 4, along with muscle issues in the mouth. I also didn't have enough milk.
After a few months it worked and worked well - he nursed until he was 3.
Then when I had my second, I knew more about what I was doing and was better prepared. But a couple of days after discharge I had to be hospitalized again, so daddy had her on formula, since my milk took 5 days to come in. Once home, we nursed and nursed. She loved it and got plump (too plump). Both she and my son had tummy issues. I took them to bed so it wouldn't be so hard to wake up to feed them. I had too much milk. It would squirt all over her little face as I was opening my bra to feed her.
She's now 3, weaned at a little over 2 and very healthy (not plump anymore!).
As far as what to do, the best advice is to drink a lot of water, relax and try not to stress, and get help for the chores, baby, house, etc., even if you have to pay for it. Teenagers can be a big help. Take some time for yourself, and give baby to daddy so you can have some alone and sleep alone time. Stress, starvation and dehydration will stop that mild from coming. Nurse as much as you can, but, especially in the beginning, don't feel guilty if you have to use some formula. Many babies do just fine with it, but breastmilk is still the best, and there are studies to back it up. The most important thing is to be sure the baby is getting something to eat, and you can supplement either way. I did, and before 3 or 4 months was up. we nursed full time.
And get the My Brest Friend (I got mine at BabyCenter.com, but I think BabiesRUs carries them now). Much better than a boppy.
Chamomile tea is good for both you and the baby, so stock up on that.
The brewers yeast, mother's tea and all that (someone even suggested beer!) did nothing but upset both my and my baby's tummy. No thanks. Didn't do the beer because I don't like it anyway, and it also upsets my tummy. Same with fenugreek.
Good luck!
