Hi again~
I just posted a reply on your other post on baby not drinking EBM...
I think 2 oz from ea. breast is pretty good for an 8 wk old...considering Tracey says your baby probably gets a whole other ounce out of you that you can't get with a pump. Also, you said that you're pumping while your husband is giving the bottle (that's what I do too) so I'm assuming it's late in the day right??? If that's the case, your milk supply could be low just because it's late in the day, which is really common. Try pumping right after the first morning feed too, since you tend to make the most milk at night and there still might be some left in there.
So, I say YOU'RE DOING GREAT!!!!!!! and stick with it. Your baby could be going thru a growth spurt as well right now, which could explain the fussiness. My LO went thru a stage, when he was that old, where he just thrashed around at the breast. My LC said to put him to the breast earlier than scheduled to avoid him getting too excited. It sure helped...and I also made a better effort to make sure any burps came out.
So just hang in there and don't stress too hard about the "why's." If your baby is gaining weight and peeing and pooping, then have faith that your magic milk factory will produce what your baby needs. If it is a growth spurt, your body will catch up and make more with all the additional suckling. As your baby gets older, your body is going to figure out exactly how much to make, so most likely you're not going to feel really full like you were in the beginning when your body makes A LOT! You're doing an awesome job!!!
