I work in a nursery with babies 6months+ and children up to 5years old and since i started iv been gettin colds and flu alot. what could minimize this?

Time & handwashing: In time you will have had enough of the airborne viruses that your immunity builds up & these become less frequent.After a basic number you become resistant to new strains. Good hand washing around diaper changing & working with toys or bottles also helps. Adults put their hands to their face often & transfer viruses off their fingers leading to illness.
