We are so past all the baby stages here in our house that it is hard for me to even remember what those days were like.... but I CAN still recall the lack of sleep and the stress of "are we doing this right" that so often accompanied the baby days.
One big struggle for me was the issue of what to feed Maggie, Kate, and Sarah when my breast milk supply could no longer keep up with their demand. I had the guilt of Ella's never even having sampled formula to add to my concern for their nutritional needs, but the fact of the matter was they were hungry and they required 3 times as much milk! By the time they were 7 months old I just couldn't make enough to go around. Fortunately a company provided us with quite a bit of their brand formula through a program that they offered to families of multiples. Once that supply was gone, being a thrifty shopper and a scientist (MS in Analytical Chemistry) I simply compared the labels on national and store brand formulas and ended up using Target's house brand formula for the few short months that we needed the supplements.
Apparently my decision was a solid one as there is currently a national campaign to make sure parents realize that store-brand infant formulas are nutritionally equivalent to, and confer the same developmental benefits as, the more expensive national brands
