Re: sleeping through the night and breast feeding
Are you at home with the baby, and feeding on demand? If so, no need to worry about her sleeping through, since any decrease in nighttime supply will be compensated for by demand feeding during the day. If you're back at work, and relying on the pump during the day, then you may not want to allow your LO to sleep through the night, since you won't have her to boost supply during the day by increased demand.
Your pump output is normal, BTW. Not low. Remember, breastfed babies only take about 2-4 oz at the breast when they nurse, and the pump is not as effective at getting milk from the breast as the baby is.
