I honestly know quite a lot about breastfeeding at this point, and may even become an LC soon - but I know next to nothing about formula. 
I need to ask a couple of things on behalf of my friend, who is supplementing due to low supply stemming from a prior breast reduction. She is getting some donor milk, but not enough to go without formula. I noticed that she was mixing the formula INTO the donor milk - and that totally struck me as not good, but I didn't say anything at the time.
It seems to me that this is wrong on a number of levels: it's wasteful, because that way he doesn't drink as much of the donor milk as he would have if it were given straight donor milk first and then topped off with formula only if needed, and also because whatever is leftover has to get tossed! (Right? Don't you have to get rid of whatever's left in a bottle of formula? I think breastmilk is different because of the antibodies.) I also think I heard something about the different types of iron binding together and thus becoming inabsorbable.
Is there any legitimate reason to combine formula with breastmilk?
Second question, or more accurately, set of questions: I am, again, pretty familiar with breastfed poo and its variations. I have no idea what's okay or normal (relatively speaking) with formula/combo poo. I know it's supposed to be more peanut buttery, but is it okay to also be green? With EBF babies, that indicates a foremilk/hindmilk imbalance, but what does it mean with formula?
He also is going 2-3 days without pooing, and this worries me for a 2 week old baby. Breastfed babies might start skipping days when they're older, but at the beginning they're usually pooing a few times a day, right? Sometimes with every feeding.
Thanks in advance - I'm totally out of my depth here.
