Change the pillowcase each day, but leave the other bed linens alone unless the sheets get soiled. If you’re dealing with diarrhea or vomiting, wash dirty clothes, soiled linens, or stuffed toys right away. Don’t shake them -- that spreads germs. Wash with nonchlorine bleach in the hottest water possible, and dry on the hottest setting. Disinfect nearby night stands, bedposts, and changing tables, and look for things that could be germy. Wash pacifiers and toys with hard surfaces in the dishwasher.
