Re: Weight issues/weak suck?
Aw, mama! That sounds so difficult. It must be very hard to be doing everything right and yet not getting the results you deserve.
Here are some things which I would suggest, which may help:
1. Rent a professional baby scale. By weighing baby before and after feedings, and subtracting the before from the after, it is possible to get an accurate measure of how much milk baby took in while nursing. If you do weigh-feed-weigh measurements for several days, you gain a good picture of what baby's milk intake is really like. Don't do just one or two measurements and call it a day: any given feeding can be much larger or much smaller than average. You really need a lot of data before you can figure out what the real pattern is. Do not try to rely on a cheap baby scale or bathroom scale: you need something which is accurate to a tenth of an oz or so!
2. Pump. If there is a problem with supply, pumping frequently with a high-quality pump ( think hospital-grade rental) will do more for you than any supplement or drug. And if you must supplement, the ideal is to supplement with your own milk rather than formula.
3. Make sure your baby is being weighed naked, and always on the same scale. There can be significant offsets in calibration between scales.
