If not, how do you interpret the mouth motions and what do you do about this cue?
Hunger Cues or..?
If I was just BF'ing I wouldn't worry about it so much because I'd figure supply and deman just take over and balance each other. But with supplementing formula after roughly every other BF session, I worry that the seemingly endless bottles mean she may be overeating out of compulsion and the fact that I can't tell a desire to comfort nurse from genuine hunger.
For example, she is 1wk old and took 24oz of formula yesterday. That seems like a lot, but maybe just because of how much it humbles my supply...
if the baby is getting to the point of crying/fussing they are past the early ques and are upset and will have a harder time nursing because they have to settle down first. it is usually pretty important to watch for those first very early ques so they don't get to the crying phase.
if you can only comfort nurse and must supplement with formula it doesn't hurt to offer the breast first, and if the baby seems to actually want to eat then feed them, and then offer the breast for comfort afterwards.
also, just because you can only pump small amounts, that isn't really and indicator of how much milk you are actually making. that doesn't mean you should not supplement if that is what your baby needs, just saying you never know how many ounces you truly make because babies are much better at getting milk out than any pump. :)
Can you get to a LLL meeting or nursing group meeting? Sometimes it's helpful for a leader to see what's going on for the best advice, though it sounds like rooting to me. If you scroll down this article there's stuff on support http://www.llli.org/llleaderweb/lv/lviss2-3-2009p4.html You may already be aware of it :)
I'd still keep offering breast, and wear in a sling/as much skin contact as possible. kellymom has some info/ideas as well to help.
Whatever you do, do not be too hard on yourself.
Not sure on formula/amount. It goes by weight, but if she's getting some breastmilk, it will change-here's a general- http://www.babycenter.com/0_how-to-tell-how-much-formula-your-baby-needs_9136.bc I would offer breast first and then formula, because if she gets full with formula, she wont' latch on to nurse.
That is fantastic your pediatrician is bf friendly. Some just tell you to give up, even if you don't have a real situation, like you do. There are foods and herbs you can take too to help, you never know what will help. I'm guessing that you have family or dh support too and that's wonderful. It makes a world of difference in your choices.
