Disinfecting toys on a regular basis as stated by the other posters, constant handwashing before meals and after being outside and my pet peeve of all - shopping carts! I urge the Moms in my daycare to carry a small package of wipes in their purses to wipe their child's fingers after shopping or coming out of a mall. I see children at a doctor's office or public place playing with germy toys then putting their fingers on their face and they have just contaminated themselves!
