Dear PixieDust,
First of all I would agree with your pediatricians and lactation consultants. I am a mother of two, had breastfeed my 1st baby till 6 months of age and the 2nd one, I breastfeed from baby until now(she is 5 years old). I also suffered low hb(8-10) but its the determination that keeps me going.
Stress would send wrong signal for your body. You must be confident that you can breastfeed. I believe you probably had researched for solutions. The web has a lot of information from the forums that you can benefit from.
I personally believe, to be able to breastfeed, you as the mother must receive enough nutrition to, in another way, feed the baby. Then keep a note on your fluid intake. I've mentioned to many people including my friends, to produce milk, make sure you are well hydrated because you are feeding the baby. If you don't drink enough, how do you expect to produce milk for the little one?
On supplements, I believe, if I don't remember wrongly, the herb feguneek will help to boost the milk supply. Alternatively, for Chinese, we believe to have abundant supply is to cook green papaya soup with anchovies. I never actually needed to supplement because
1) I drank a lot of fluid every hourly, i.e. at least 1 glass of hour an hour or two.
2) I make sure my baby was breastfeed every 2 hours(its awfully tiring after birth but the gap increased when the baby grows). I think by now your baby should be drinking every 3-4 hourly?
3) After my baby was breastfed, I pumped our the excess milk and store it in the fridge/freezer(you will have to decide when you need to use those). Afterall, we don't produce every 2-3 hourly at times, then these milk stored in the freezer will come handy.
4) I did supplement, its only 1 tin on the 1st month. Other months, I still keep the tin handy but her older brother helps to finish up my milk formula most of the time.
5) Even I work, I still find time to express the milk and store in the fridge for the baby.
I hope the above would give encouragement for you to keep on going. Don't think being a thal you are not able to do it. If I can do it, you can do it too. The most important thing..... you need to be well informed, therefore, look for the web forums. Some mothers are having same predicament, you can benefit from their sharing.
Good luck.
