We just started supplementing breast milk with formula and I have done almost no research. We're using a special hypo=allergenic type on the dr's recommendation due to a family history of allergies and Dante's, already proven, sensitive skin (he's allergic to the WATER here. Oh, what fun). It comes in powder with no ready made option.

My question is: how long once you make up a batch of formula does it last? I've been chucking it if it has been more than 24 hours, but now I'm wondering if I need to be that careful--or am I being not careful enough? Does it need, like breastmilk, to be stored in the fridge once made? Can it be reheated, or once it's been reheated how long is it good for? I feel like such a newbie and the box was less than forthcoming (well that, and it was in German...)

TIA!
