Re: White nipples when pumping & low milk supply
Welcome to the forum and congratulations on the new baby!
The most likely explanation for the white nipple you're seeing is something called a vasospasm, which is a sudden and usually quite painful constriction of the blood vessels in an extremity, in this case the nipple. You want to treat the vasospasms with heat and attempt to prevent them by using correctly sized shields and by starting your pump off at a low speed and only gradually turning it up. If you can keep your body generally warm, by doing things like wearing warm clothes and socks or slippers, that should also help.
Your pump output actually sounds fine. 100 ml is 3.38 fluid oz, which is a normal amount of milk to pump. Remember that the average feeding is just 2-4 oz (that is, 59-118.3 ml), though it is very common for babies to take significantly more than that when they are eating from the bottle instead of the breast. The bottle flows a lot faster the breast, delivers a fast flow even when the baby is nursing solely for comfort, and it is easy for even the most sensitive bottle-feeding parent to encourage a baby to drink a little faster or to take the last few ml in a bottle even when the baby is full.
Not feeling full means nothing. When a mom's supply is well-matched to her baby's needs, she will rarely if ever feel full. Fullness is something a mom experiences only when she's making more milk than her baby needs.
How much formula are you using per day? And how often are you using the bottle?
