I am bfar. I dont really reccomend it. I nurse all day. I take all kinds of herbs. I pump twice a day (sometimes 3 times) and I still have to supplement. It could be worse, but its not easy. and my breasts are almost as floppy as before (although I think they are smaller, but they are still big, I was reccomeded to get a 36F nurseing bra from birthandbaby when I emailed them. I was a 34DD/E or so before my surgery, and a 34C after). I have used a finger feeder, a lact-aid, and a sns. even with the supplement my 6 month old is small at 12lbs.
from all that I have read it seems that most bfarers can provide about 50-100% of the milk thier baby needs. I fall into that at about 75-66%. My baby currently gets 8oz of formula a day, and every few days (or week) when I have pumped enough she gets 4oz milk and 4oz formula.
I think its really a question of: how much supplement can you live with giving to your baby? do you have the ability/desire to get donor milk? if not are you ok with giving formula? with donor milk or formula are you emotinally ok with it? are you prepared to deal with the alternative means of feeding (sns, bottle, etc) (purchaseing, cleaning, dripping, tapeing, etc)?
once you know you are done having kids/bfing. definatly get it done.
pm me if you have any more questions (at least point me back, I might not see them here)
