In addition to coughs, sniffles, and sneezes, you'll also have to deal with the bumps and bruises your baby will encounter in spite of your best efforts. Certainly she'll increase her exposure once she's mobile, but even infants can get bumped, burned, or scratched. You'll find a hundred things to do to childproof your home, and your baby will probably find a hundred more things to get into. Prevent what you can, and know how to treat the rest.
