Wash your hands, wash your hands, wash your hands...
and then wash your hands again. Teach your kids to do the same.
Several of the mom's I work with take their scrubs
off in their garages like the poster above.
Generally, healthy people and their kids don't get sick, because we have our defenses such as skin, nose, friendly germs that crowd out the bugs that might make us sick, etc. One of those lines of defense is intact skin, so when your kids get those everyday cuts and lacerations be extra diligent in keeping yourself and the wounds clean. I've heard of some kids getting MRSA infections.
Good luck and don't worry too much about it. There's not much literature about kids getting sick from moms who are nurses, because it's more than likely rare.
