I love the infection idea. We have similar issues like that on our unit. There is also lots of info on co-bedding twins (in the same crib or isolette) and kangaroo care (when it should or should not be done), NICU staff wearing their own scrubs or hospital issued scrubs (does it effect infection rates), breastmilk (are their medications that Mom takes or diseases/infections that Mom has to make it unsafe).
Good Luck!
