Huh?
I'm just a nursing student, but I'm pretty sure you're right about baby's immunes systems being weaker than ours...isn't that a no-brainer? Isn't that why babies are constantly having ear infections & colds? But, let's say for arguments sake that infants do have a stronger immunity system than ours

...I think another piece of the puzzle is that when babies acquire certain illnesses (TB & meningitis being classic examples), the long-term effects are much more devastating than if adults were to acquire the same illness.
Who's making up your assignments? When I worked as a CNA, the nurse that had actually worked the floor the shift before made up our assignments. CNAs were never allowed to work with say, one pt that had pneumonia & an infant on the same shift. You can bet the mother of that baby would certainly have something to say if she knew about it!
